SNAKE CREEK LASERS LLC — Department of Defense SBIR Phase I: This topic addresses the need for compact efficient solid-state deep ultraviolet (UV) lase

Description

This topic addresses the need for compact efficient solid-state deep ultraviolet (UV) lasers operating in the wavelength range of 220-250 nm, for use in Raman systems for chemical and biological detection. The laser to be developed would also be very useful in the detection of explosives. We propose to develop an efficient 946 Q-switched nm laser system that is efficiently quadrupled to 236.5 nm. The laser system will produce excellent beam-quality and high pulse energy. It will operate single longitudinal and transverse mode. During Phase I we will generate a detailed design for the compact deep UV laser, complete experimental testing of candidate nonlinear crystals to be used for deep UV generation using existing high power lasers, generate detailed engineering device drawings for a Phase II demonstration, and develop a technology roadmap leading to a compact, efficient deep UV laser system with a volume of<1800 in3 and a weight<25 pounds. In the Phase I option we propose to demonstrate an integrated long-pulse Q-switched Nd:YAG laser that operates in both single longitudinal and transverse modes.
