Seems like they will be there before we know it. First off in defensive capabilities, then I am sure we will see them in the hands of soldiers.

http://www.spacewar.com/reports/Raytheon_Tests_New_Laser_Weapon_999.html

Raytheon announced Monday that it had "successfully tested a prototype solid-state laser weapon." The new laser system "combines the proven capabilities of the Phalanx weapon system with the power and effectiveness of lasers to defeat rockets, mortars and missiles at an operationally significant range," the company said.

Raytheon said its prototype solid-state Laser Area Defense System, or LADS, "successfully detonated 60-millimeter mortars at a range greater than 550 yards within the tactical timeline in static ground testing conducted in partnership with the United States government." The company described the tests as "groundbreaking' and said the results had been achieved "in less than six months."

"The LADS demonstration used a proven, existing, off-the-shelf solid-state laser, coupled with commercially available optics technology," Raytheon said. "The goal of the demonstration was to rapidly prove that lasers can yield military utility now by demonstrating that such a system could protect warfighters against mortars."

"Secondary goals of the demonstration were to offer a near-term alternative to chemical lasers, which may create logistics challenges for the warfighter, and to prove that existing optical and targeting components can significantly lower total laser system costs and speed their ultimate transition to the warfighter," the company said.

Raytheon said its solid-state laser technology also ensured that the operation of the LADS was "safe to the environment, does away with the need for caustic chemicals and radically reduces the life-cycle cost."

What is impressive is the following quote where they talk about how the idea became reality in less then 6 months.

"In just six short months, Raytheon and government engineers went from an idea to operational field testing of a solid-state laser system that offers the potential of near-term protection for our troops," said Mike Booen, vice president of Advanced Missile Defense and Directed Energy Weapons at Raytheon Missile Systems in Tucson, Ariz. "Our solid-state LADS proves you don't have to wait another three to five years for solid-state lasers to have military utility on the battlefield. They are ready now, with no chemicals required."

Its probably a differnet system but I read a similar headline at http://www.space.com/spacenews/. Of course, I can't spend $150 annually but thought about it. Here is something similiar and about a month ago a Raytheon system mentions. I can't remember if it was a LADS. Still look at this qoute from page. It could be part of a larger network. This probably base on probablity in need. If there isnt much threat, work could delay output until closer to a threat. I also read where some commerical airlines will equip with a similar system. This is so other assest can manuver freely. Awhile commerical fuel is used often enough...
WASHINGTON -- The Senate Armed Services Committee cut all funding for the Alternative Infrared Space System (AIRSS) missile warning system in its version of the fiscal 2008 defense authorization bill and cut $200 million from the president’s request for the Airborne Laser boost-phase missile defense program. The House Armed Services Committee had cut $250 million from the Airborne Laser system.

It is just a matter of time before we see our troops carrying them into battle.
I wonder what steps would be taken to prevent them from falling into enemy hands?

Put GPS on them? Then if they are reported lost activate some remote circuitry that fries the electronics?

Laser range finders have been used for 20 years.

I am referring to the "ray gun" aspects of the Lasers.
You know, fire and they get burned through and dead type. :)

It'll be a while before you see ballistic weapons replaced by energy weapons for infantry. The power requirements are substantial, and the problem of "ammo" portability hasn't been solved yet.

How long would you say it might take? If you look at the progression of computers, and how electronics have gotten smaller, is that a benchmark to use for lasers?

Dunno - could be a very long time. Power miniaturization hasn't been nearly the priority, nor has efficiency, that electronic computing power and miniaturization has.

That's the battery pack for a 67kW laser - less powerful than necessary for a vehicle-mounted weaponized laser. And it says nothing about being able to make multiple shots in rapid succession, or how to rapidly recharge the power source.

Currently, they are talking about perhaps reaching the 100kW power level necessary for a mobile platform weapon by the end of this year, and it'd take a 9m long trailer to accomodate. We're probably at least a few years out from a fieldable laser system.

Realistically, to store and generate the power necessary even for a "low power" laser rifle, I think we need a physics breakthru in energy storage. We're talking a revolutionary advance in basic science. Who knows when that might happen. (Not I!)

BTW, we are approaching the physical limits for miniturization of circuitry, given what we know about physics. That's why newer computers are not faster and smaller - they have multiple cores.
