Description

technical field [0001] The invention belongs to the technical field of laser amplifiers, in particular to a solid-state laser amplifier capable of effectively suppressing parasitic oscillations. Background technique [0002] Since its invention, laser has been widely used in various fields of science and industry. An important aspect of this application is as a driver for inertial confinement fusion (ICF) and inertial fusion energy (IFE) and for providing extreme material conditions. In such applications, the laser beam is required to have very high energy or extremely high peak power, so the amplifier in the laser device needs to have a high gain. However, in high-gain solid-state laser amplifiers, spontaneous radiation is easily reflected by the side of the gain medium to form parasitic oscillations, which seriously consumes the energy storage of the gain medium and reduces the overall efficiency. [0003] At present, the main method for suppressing parasitic oscillation...
