Big Freakin' Laser Beams In Space 142
schnippy writes "Esquire is running an interesting article on the work on adaptive optics and directed energy being done at the U.S. Air Force's Starfire Optical Observatory. This facility was the subject of a New York Times article earlier this year which suspected the facility was conducting anti-satellite weapons research under the cover of astronomy."

The space elevator will move too slowly to keep living things from being irradiated by the Van Allen belt surrounding the Earth. The solution is to create a passenger compartment inside a cargo container filled with water, which is a terrific absorber of energy, which in turn can house the sharks.

Does anyone have any experience with peak power on these laser diodes?
I recall from working with similar units ages ago that it's far less than average power, but still pretty significant.
(A LED is basically thermally limited, so at a low duty cycle your peak can approach achieve many times the "rated" power...
Laser diodes used in pulsed mode are nowhere near that, it's a power vs area thing, basically the point at which they blow their tiny mirrors/facets off...)

My Starfire Story (Score:4, Informative)
After we got to the top of the mountain, we went into the main building. There were a couple of dudes in suits there. I was introduced, but I don't remember who they were. Not sure if they were Congressional types or Pentagon guys or what, but the people who worked there were nice to them so I tried to be on my best behavior. We got a short lecture about the project and some of the photos they had produced were handed around.
In case you didn't RTFA, the purpose of Starfire is to use a projected laser dot to configure an adaptive-optics mirror to compensate for atmospheric distortion and allow for better terrestrial astronomy. It works pretty damn good too. The photos I saw were very impressive. Better than Hubble in some cases, which they were justifiably very proud of. They sure were a helluva lot cheaper to get than Hubble photos.
After the lecture we got a tour of the facility. There were several telescopes on the mountain, a couple of which were capable of projecting a laser. The main 'scope had a really neat setup where they could have several experiments going at once and rotate a mirror to pick which one went up the tube. Other than that there were the optical experiment tables, the adaptive-optics setup, the imaging system, and several different kinds of lasers of varying impressive powers.
Next we went into the main dome. We were informed that the main telescope could depress below 0 degrees and the dome could be lowered in 30 seconds, and raised in two minutes by machine, or ten minutes if the hand cranks had to be employed. At the end of the telescope I spotted a disc with "Raytheon" on it. I casually asked, "What's the radar for?"
"To make sure there are no aircraft entering the beam path," the tour guide replied. The suit dudes were very surprised by my question so I mostly shut up for the rest of the tour. We then exited the platform so they could open the dome and slew the telescope.
Next came the control room. There were a bunch of guys in there, some in uniform and some in civvies. The were all business and didn't say much. They showed us the computer that had the ephemeris of every object in orbit down to the size of a quarter. All the computers were UNIX and X Windows, FYI. As a software guy, I thought the interface left something to be desired, but that's just me. Tracking an object with the 'scope was as simple as clicking on the desired target. We watched the 'scope slew through a CCTV monitor located near the target computer. Sadly, conditions were unfavorable for a test firing, so I didn't get to see the big mother fire.
Last they took us down to the "shack" where the guide-star laser was produced and sent through a smaller scope. The guys in here were friendlier, hippie/scientist types. I rapped with them a little while the brass talked amongst themselves. They were really excited about their laser because it was very powerful and very yellow, which worked out good for their astronomy.
Understand, the men who worked on this project never, ever said anything about it's use as a weapon. They always talked about it in terms of the astronomy. They had a nice telescope with a honkin' big laser under it, a radar on the front of it, and a computer that could track the 'scope on every object in orbit, up on a mountain in the middle of nowhere, but officially the fact that Starfire could be used as a weapon never occurred to them

In my book, that's cheap insurance against events that would be significantly more costly to the country than 4 airliners.
