Description

technical field [0001] The invention relates to the field of optical technology, in particular to a solid-state laser life test device. Background technique [0002] The 3-5μm band is not only the atmospheric infrared window with the smallest attenuation, but also covers the absorption peaks of many atoms and molecules in this band. Therefore, lasers in this band are very important in many fields such as spectroscopy, remote sensing, medical treatment, and environmental protection. application value and prospects. This makes the research on the 3-5μm band laser become a very hot topic in the world at present. [0003] In terms of the output of solid-state mid-infrared lasers, optical parametric oscillation (OPO) technology is currently mainly used, using KNbO 3 , LiNbO 3 , KTP, KTA, AgGaS 2 , AgGaSe 2 , PPLN, ZnGeP 2 Isocrystal effectively achieves laser output in the mid-infrared band through OPO technology. Mid-infrared laser output power from 1W level AgGaSe in the...
