NOT KNOWN FACTS ABOUT HGGA2S4 CRYSTAL

053 μm. The absorption spectrum of ammonia was introduced to demonstrate the feasibility from the developed optical parametric oscillator procedure for spectroscopic measurements and fuel detection.We report on a femtosecond optical parametric oscillator (OPO) to the deep-infrared (deep-IR) based upon the Kerr-lens-manner-locked Ti:sapphire laser
