THE SMART TRICK OF HGGA2S4 CRYSTAL THAT NOBODY IS DISCUSSING

053 μm. The absorption spectrum of ammonia was offered to show the feasibility with the designed optical parametric oscillator method for spectroscopic measurements and fuel detection.We report with a femtosecond optical parametric oscillator (OPO) with the deep-infrared (deep-IR) based on the Kerr-lens-mode-locked Ti:sapphire laser since the pump
