U.S. weapons maker Northrop Grumman Corp has revealed some details of U.S. Army Stryker vehicle high energy laser initiative. The
Diesel generator is powering radars if they get hit the SAMs and everyone operating them are already as good as deadI fail to read a strategy behind this. As a defensive system it will pose a major risk to the zone protected. Hit the reactor and it's all area that is doomed. Wherever this will show up, it would be a high priority target in order to force your opponent to stand down and runaway
For now it is mostly aimed at covering ICBM sites, namely from satellites. And what is supposed to take out ICBM site? Another ICBM. So it barely matters if your reactor (of it's really there) will add few digits after dot of fallout.I fail to read a strategy behind this.

Unless the frequency is perhaps doubled the value of this laser as a weapon will be very limited. The attenuation of 2.03 micron radiation in air is very high. Frequency doubling is generally possible but would reduce the efficiency, power and energy achievable.Thoughts on Nuclear fuel pump lasers?
“In 2012, the source  reported that in the RFNC-VNIITF (Snezhinsk) a gas laser pumped by a nuclear reactor operating at the atomic xenon transition with a wavelength of 2.03 μm was created. The output energy of the laser pulse was 500 J at a peak power of 1.3 MW. This device is the most compact in terms of the volume of active gas medium used (specific laser radiation energy was 32 J / dm³)”
Sound to me as the most serious effort yet in the world for Space beamed energy. Amazing that it has to be the military with all the talks around fossil energy and climate change.Meanwhile, AFRL also is considering space-based power generation. Under the Space Solar Power Incremental Demonstrations and Research program, AFRL will investigate using high-efficiency solar cells on a spacecraft to absorb the solar energy. The spacecraft then would convert the solar energy into a radio frequency transmission and beam it to a base to supply energy. AFRL has awarded Northrop Grumman a $100 million contract to begin developing the technology.
The Space Solar Power Incremental Demonstrations and Research program (SSPIDR) really does sound interesting though details seem to be very scarce. Basically all I could find was AFRL's own press release which was then copy-pasted on a few websites. With $100M I hope it comes to something, I can imagine both military and civilian applications. While we really don't - and won't - have singular silver bullets to mitigate climate change in the quite constrained time frame available to meaningfully avoid truly chaotic runaway effects, having more options to chip away at the core problems is always welcome.Sound to me as the most serious effort yet in the world for Space beamed energy.

Get Greta some fatigues...
W/o PBs to deliver KE effects w/ DE speeds the problems is still not solved. (Hybrid Chemical maybe ...pushin it).
“If I look back over multiple decades, [across] many different concepts – starting with CO2 Laser, CO lasers, chemical lasers, free-electron lasers, chemical oxygen-iodine,” Karr said, “every one of those… at some point we hit a level where problems were very, very challenging.”DoD is finalizing contracts for three competing demonstrators, aiming for a 300-kilowatt weapon by 2022 and 500 kW by 2024, laser R&D director Thomas Karr told us.breakingdefense.com
