Description

technical field [0001] The invention relates to the technical field of laser gain medium measurement, in particular to a multi-angle and multi-point measurement device and method for laser gain medium wrapping residual reflection. Background technique [0002] Laser gain medium is widely used in various high-power and high-energy lasers, and has become the most important laser working substance. Laser working substances are divided into solid, liquid and gas. Among them, solid-state laser is the most important one. It not only activates high ion density, wide oscillation frequency band, and can generate light pulse with narrow spectral line, but also has good mechanical properties and stable chemical properties. [0003] The basic conditions that the laser gain medium used for solid-state lasers should have are: suitable spectral characteristics, small excited state absorption, good optical uniformity, stability and physical and chemical properties. Its materials are mainl...
