Powerful Optical Parametric Oscillator (OPO) on GaSe Crystal Pumped by an 3-Micron Laser

摘要

The proposed research should demonstrate an extension our project on resonator optical parametric oscillation (OPO) in a GaSe crystal pumped by an switched three micron laser. Our previous work demonstrated feasibility of obtaining of resonator-type OPO on GaSe. At this phase we were concentrating on obtaining powerful tuneable IR radiation. The work should consist of improving of pump laser system and architecture of GaSe OPO in order to have (caret) 10 mJ tuneable IR near 6 micron with 20% conversion efficiency.
