[0022] See figure 1 , figure 2 with image 3 As shown in the figure, a solid-state slab laser pumped by a semiconductor laser side-pumped consists of a laser solid-state slab 1, a semiconductor laser pump source 2, an optically shaped cylindrical microlens 3, and a back cavity mirror of the laser resonator 4, The output mirror 5 of the laser resonant cavity and the cooler 6 are composed. The laser solid slab 1 is a single-structure thin slab. On both sides, that is, in the width direction, a semiconductor laser pump source 2 is provided, and an optical shaping cylindrical microlens is provided. 3 Set between the semiconductor laser pump source 2 and the laser solid slab 1, the pump light emitted by the semiconductor laser pump source 2 passes through the optically shaped cylindrical microlens 3 and then forms a one-dimensional parallel light with a rectangular cross section. The laser solid slab 1 enters at the middle position of the side surface, the beam diameter of the pump li...
