THE BASIC PRINCIPLES OF HGGA2S4 CRYSTAL

053 μm. The absorption spectrum of ammonia was presented to show the feasibility from the made optical parametric oscillator system for spectroscopic measurements and gas detection.We report with a femtosecond optical parametric oscillator (OPO) for your deep-infrared (deep-IR) according to the Kerr-lens-mode-locked Ti:sapphire laser given that th
