HGGA2S4 CRYSTAL NO FURTHER A MYSTERY

053 μm. The absorption spectrum of ammonia was introduced to demonstrate the feasibility from the formulated optical parametric oscillator program for spectroscopic measurements and gas detection.We report on a femtosecond optical parametric oscillator (OPO) for the deep-infrared (deep-IR) according to the Kerr-lens-method-locked Ti:sapphire laser
