5 SIMPLE TECHNIQUES FOR HGGA2S4 CRYSTAL

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