本文提出一种用非球面光学和薄圆片形激活元件的紧凑的固体激光器系统,用半导体激光阵列的辐射从底面泵浦激活元件。共振反射镜、二极管阵列、激活元件和致冷系统连接在一个装置中。表明在激光器的组成中采用混合式的装置——不稳谐振腔,能减小聚焦激光束衍射的散射并导致在焦点处功率密度的增加。所探讨的激光器系统在建立最小 This paper presents a compact solid-state laser system using aspheric optics and thin wafer-shaped activation elements that pump the activation elements from the bottom with the radiation from the semiconductor laser array. Resonance mirrors, diode arrays, activation elements and refrigeration systems are connected in a single unit. It is shown that the use of a hybrid device, an unstable resonator, in the composition of the laser, can reduce the diffraction of the focused laser beam and result in an increase of the power density at the focal point. The laser system in question has been established to a minimum
