LITTLE KNOWN FACTS ABOUT HGGA2S4 CRYSTAL.

053 μm. The absorption spectrum of ammonia was introduced to exhibit the feasibility in the developed optical parametric oscillator technique for spectroscopic measurements and gas detection.We report on a femtosecond optical parametric oscillator (OPO) for your deep-infrared (deep-IR) determined by the Kerr-lens-method-locked Ti:sapphire laser as
