5 SIMPLE TECHNIQUES FOR HGGA2S4 CRYSTAL

053 μm. The absorption spectrum of ammonia was introduced to reveal the feasibility of the created optical parametric oscillator method for spectroscopic measurements and gas detection.We report on the femtosecond optical parametric oscillator (OPO) to the deep-infrared (deep-IR) based upon the Kerr-lens-manner-locked Ti:sapphire laser since the p
