CONSIDERATIONS TO KNOW ABOUT HGGA2S4 CRYSTAL

053 μm. The absorption spectrum of ammonia was presented to demonstrate the feasibility of the made optical parametric oscillator process for spectroscopic measurements and gas detection.We report with a femtosecond optical parametric oscillator (OPO) with the deep-infrared (deep-IR) based upon the Kerr-lens-manner-locked Ti:sapphire laser as the
