阅读说明：本技术 一种多腔镜拓扑结构的调q脉冲激光器 (Q-switched pulse laser with multi-cavity mirror topological structure ) 是由 刘海 于 2021-08-31 设计创作，主要内容包括：提供一种多腔镜拓扑结构的调Q脉冲激光器,包括沿光学路径从左向右依次设置的全反镜(1)、激光模块(4)、调Q开关(5)和输出腔镜(6),所述全反镜(1)、激光模块(4)、调Q开关(5)和输出腔镜(6)构成激光振荡输出谐振腔,用于输出大能量高重频窄脉宽的脉冲激光。沿光路方向在全反镜(1)和激光模块(4)之间设置一个多腔镜拓扑结构,同时也可以在调Q开关(5)和输出腔镜(6)之间设置一个多腔镜拓扑结构,所述多腔镜拓扑结构包括在光路方向上呈45°倾斜放置的分光镜(3),以及在所述分光镜(3)的正上方与正下方各布置一个全反镜(1)。通过设置多腔镜拓扑结构,分散了传统调Q激光器谐振腔内仅采用单一腔镜时其所承受的激光能量和激光功率,显著降低了单一腔镜损坏的风险,保证了调Q脉冲激光器能够在高输出功率的前提下稳定工作。(The utility model provides a Q-switched pulse laser of multicavity mirror topological structure, includes along optical path from the total reflection mirror (1), laser module (4), transfer Q switch (5) and output chamber mirror (6) that set gradually from the left hand right side, total reflection mirror (1), laser module (4), transfer Q switch (5) and output chamber mirror (6) constitute laser oscillation output resonant cavity for the pulse laser of the narrow pulse width of high repetition frequency of output high energy. A multi-cavity mirror topological structure is arranged between the total reflection mirror (1) and the laser module (4) along the light path direction, and meanwhile, a multi-cavity mirror topological structure can also be arranged between the Q-switch (5) and the output cavity mirror (6), wherein the multi-cavity mirror topological structure comprises a spectroscope (3) which is obliquely arranged at an angle of 45 degrees in the light path direction, and the total reflection mirror (1) is respectively arranged right above and right below the spectroscope (3). Through setting up many chamber mirror topological structure, laser energy and laser power that it bore when only adopting single chamber mirror in having disperseed traditional transfer Q laser resonant cavity have shown and have reduced the risk of single chamber mirror damage, have guaranteed transfer Q pulse laser can be in stable work under high output's prerequisite.)
