Now WHAT ON EARTH do we need all this mega fire power for?
[edit on 24-8-2009 by zorgon]
Airspace is monitored at night when objects in space reflect sunlight and the reflection provides the complex with the necessary information. Okno is fully automatic. It may operate without human supervision, keeping track of the known and newly detected objects. Since the complex operates in the passive mode, it does not use too much of electric power. (In fact, it needs as much as a house of 150 apartments uses.)
The US Department of Defense has three similar objects. They use lasers and therefore require more by way of electric power.
Although very impressive progress has been made in overcoming the distorting effects of the atmosphere, beaming laser power to satellites with diffraction-limited divergence still requires considerable development. There are numerous engineering and procedural difficulties that must be overcome. We will attempt beaming laser energy to two orbital bodies (the moon and COMSTAR-4) to make accurate measurements of the state of the art in capability, identify the major areas of present difficulty, and explore ways of overcoming those difficulties.
The division’s primary focus is on advanced optics for the detection and tracking of hostile targets. In support of the Air Force’s Airborne Laser program, this division is investigating how to use optics to precisely place a beam of laser light on a moving target at greater and greater ranges.
Operates autonomously, above the clouds, outside the range of threat weapons but sufficiently close to enemy territory
Proposed cuts in missile-defense programs will greatly scale back Boeing's airborne-laser program; the budget maintains funding for more research but cancels a second prototype aircraft.
In the 1990s, NASA and the U.S. Air Force Space Command studied a concept called Orion, sometimes called a "laser broom," designed to eliminate small debris. A ground-based laser would be aimed at each object until pressure from the beam, coupled with the reaction force from material ablating away from the target, sends it into a lower orbit.
Orion, though, "turned out to be not all that easy technically," says Johnson. And with an estimated cost of $500 million, "it was certainly not within anybody's budget." The system would have required its own tracking network, since current space surveillance cameras track objects only down to 10 centimeters. Engineers would have to work out a system that imparted enough momentum to move a chunk of debris and that would be sure to lower instead of raise its orbit. "There are lots of little gotchas in the Orion final report," Johnson says. "There's a reason why it's been sitting on the shelf for more than a decade."

Your car engine creates thousands of small explosions from the fuel/air mixture. There was one point where they tried creating engine fuel from gunpowder for cars, but it proved unreliable. Thinking along these lines, then the explosion could provide a short powerful burst of electrical energy
As for why they would develop such a weapon? I don't know if any of you remember a film called "Spies like us" (Dan Ackroyd & Chevy Chase) but the military use a weapon in the film that bounces a high energy beam off a satellite(s) to hit a designated target on the other side of the planet.
To demonstrate the ability to fabricate the large mirror required by an SBL, the Large Advanced Mirror Program (LAMP) built a lightweight, segmented 4 m diameter mirror on which testing was completed in 1989. Tests verified that the surface optical figure and quality desired were achieved, and that the mirror was controlled to the required tolerances by adaptive optics adjustments. This mirror consists of a 17 mm thick facesheet bonded to fine figure actuators that are mounted on a graphite epoxy supported reaction structure. To this day, this is the largest mirror completed for use in space. This LAMP segmented design is applicable to 10 m class mirrors, and the Large Optical Segment (LOS) program has since produced a mirror segment sized for an 11 m mirror. The large dimension of this LOS mirror segment approximates the diameter of the LAMP mirror
Megawatt class power levels were first achieved by the Mid-Infrared Advanced Chemical Laser (MIRACL) originally sponsored by the Navy, later by DARPA, and then by BMDO. Because the design was intended for sea level operation, the MIRACL laser does not achieve the optimum efficiency necessary for space-based operation. DARPA launched the Alpha laser program, with the goal of developing a megawatt level SBL that was scaleable to more powerful weapon levels and optimized for space operation. In this design, stacked cylindrical rings of nozzles are used for reactant mixing. The gain generation assembly achieves higher power by simply stacking more rings. In 1991, the Alpha laser demonstrated megawatt class power levels similar to MIRACL, but in a low pressure, space operation environment. Alpha demonstrates that multi-megawatt, space-compatible lasers can be built and operated.
The ability to control a beam was demonstrated at low power under the Large Optics Demonstration Experiment (LODE) in 1987. The current high power beam control technology is now being integrated with the Alpha laser and the LAMP mirror in a high power ground demonstration of the entire high energy laser weapon element. This is known as the Alpha-LAMP Integration (ALI) program.
In 1985, the Talon Gold brassboard operated sub-scale versions of all the elements needed in the operational ATP system including separate pointing and tracking apertures, an illuminator, an inertial reference gyro system, fire control mode logic, sensors and trackers. Talon Gold achieved performance levels equivalent to that needed for the SBL. In 1991, the space-borne Relay Mirror Experiment (RME), relayed a low-power laser beam from a ground site to low-earth orbit and back down to a scoring target board at another location with greater pointing accuracy and beam stability than needed by SBL. The technology to point and control the large space structures of the SBL was validated in 1993 by the Rapid Retargeting and Precision Pointing (R2P2) program

It seems to me that the Russians are saying that, unlike the US systems, Okno does not utilize lasers, and so does not have the power requirements of the US systems.
Of course it's theoretically possible that the system could work in reverse but titles of papers and abstracts don't usually tell the whole story.
You've listed this one twice for some reason:
Phillips Research Site
The Phillips Research Site pages are organized to support Air Force Research Laboratory's Directed Energy (RD) and the Space Vehicles (RV) Directorates and are structured in such a manner that some site functions overarch both directorates. Those site specific support functions include Business Opportunities, Employment and the AFRL-PRS Reserves.

Why do you show a picture of lasers used for the creation of guide stars and imply that they are being used as weapons or energy transfer?
As a part of the directorate, the Starfire Optical Range, a world-class optical research facility, develops optical sensing, imaging and propagation technologies to support Air Force aerospace missions. Primary experiments consist of using adaptive optics to perform real-time compensation for aberrations induced by the atmosphere. In addition, the range conducts research in space object imaging, advanced tracking, nonlinear optics and atmospheric physics.

Oh, I don't know. Maybe because Starfire is part of the research being done there. Maybe because it's a cool picture. Maybe because it's a demonstration of producing a guide star for the adaptive optics they're talking about in the verbiage. ...

Guessing from the color, I'd say it's a picture of the sodium system in use,
A FASOR used at the Starfire Optical Range for LIDAR and laser guide star experiments is tuned to the sodium D2a line and used to excite sodium atoms in the upper atmosphere.
Original caption: "This sodium laser—being fired from the Starfire Optical Range on Kirtland Air Force Base, New Mexico—is used with deformable optics to help eliminate atmospheric distortions when gathering images of objects in space."
Though the caption states that this is a "sodium laser", this is actually misleading as the Starfire Optical Range LIDAR laser seen here is actually two solid state IR lasers, 1.064 and 1.319 microns, that are frequency summed in LBO within a doubly resonant cavity. The orange beam is observed due to the intense laser light scattering off particles in the air. In general, laser light travelling through a vaccum can not be seen unless aimed directly towards the observer.
The Airborne Laser (ABL) will locate and track missiles in the boost phase of their flight, then accurately point and fire the high-energy laser, destroying enemy missiles near their launch areas.
* Operates autonomously, above the clouds, outside the range of threat weapons but sufficiently close to enemy territory
* Engages early, destroying ballistic missiles in their boost phase of flight over launch area
* Cues and tracks targets, communicating with other joint theater assets for layered defense system
* Nose-mounted turret with 1.5m telescope that focuses beams on missile and collects return image and signals
* Beam Control System to acquire and track targets with precision accuracy
Look for further developments of the ABL as the global threat of ballistic missiles becomes ever more prevalent.
