HGGA2S4 CRYSTAL - AN OVERVIEW

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