HGGA2S4 CRYSTAL NO FURTHER A MYSTERY

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