Abstract

Lasers operating in the mid and long infrared spectrum are finding applications in the countermeasure as well remote sensing fields due to the atmospheric transmission windows between 3-5 um and 8-12 um¹. Compact, lightweight, efficient systems are being developed for applications where CO₂ sources have been the mainstay. With the advent of all solid state diode laser pumped Holmium lasers, providing high peak powers, new non-linear optical (NLO) materials are allowing the shifting of these sources to generate multi-watt outputs² over new spectral regions.
