[0002] A solid laser is a laser that uses solid laser material as a working substance. The working medium is a small amount of activated ions uniformly doped in a crystal or glass as a matrix material. There is a patent for a solid laser, and the patent publication number is CN114976839A. The invention discloses a solid laser, including a local oscillator stage, an amplifier stage, and a reflector group; a 90-degree optical rotation crystal is arranged between the first focusing cavity and the second focusing cavity; the connection direction of the first laser rod and the first pump lamp is perpendicular to the connection direction of the second laser rod and the second pump lamp. The solid laser of the present invention changes the radial and angular polarization directions of the laser output through the first laser rod by arranging a 90-degree optical rotation crystal between the first focusing cavity and the second focusing cavity, and then the radial and angular phases of the laser after passing through the second focusing cavity are complementary, and the output laser has no phase delay and maintains vertical polarization. The arrangement of the lamp rods in the first focusing cavity and the second focusing cavity compensates for the problem of uneven pumping caused by xenon lamp pumping, and the first pump lamp and the second pump lamp are connected in series, which can ensure that the pumping intensity of the two xenon lamps is the same, and the thermally induced birefringence effect can be ideally compensated.
