THE SINGLE BEST STRATEGY TO USE FOR HGGA2S4 CRYSTAL

053 μm. The absorption spectrum of ammonia was offered to exhibit the feasibility with the designed optical parametric oscillator method for spectroscopic measurements and gasoline detection.We report with a femtosecond optical parametric oscillator (OPO) for that deep-infrared (deep-IR) based upon the Kerr-lens-method-locked Ti:sapphire laser bec
