High Energy, Long Pulse Laser (Multispectral line long pulse solid state laser)

"The objective of the proposed effort is to demonstrate feasibility for a high power multi-wavelength long pulse (0.5-10 microsecond) visible to near IR laser system. The system will provide high power output simultaneously at multiple wavelengths suitablefor countermeasure applications. The output will be nearly impossible to filter because it will be more than three wavelengths simultaneously and at high power. The underlying technology could also be tailored in the future to provide on-the-fly dynamicwavelength changes.The proposed a solid state system has an alexandrite laser to deliver a few Joules output at 750 nm. A proprietary Raman converter generates 1 micron light (Stokes) and other visible (anti-Stokes) wavelengths. The Stokes output is frequency doubled toprovide high power green/yellow outputs at about 560 nm.This program integrates three proprietary technologies that Light Age has utilized in its custom commercial laser sources: high energy alexandrite laser output; pulse stretching to produce hard to reach 0.5 to 5 ms pulse durations; and high power Ramanconverters. Elements of the system and the basic technology developed herein will address diverse commercial needs having specific application to certain state of the art medical procedures. The technology that will be developed under this program will be very important to a number of commercial fields today and in the future. It is particularly important to cer
