摘　　要：介绍了2.7μm声光Q开关的设计、制作及应用。该器件采用氧化碲晶体作为声光互作用介质,铌酸锂晶体作为压电换能器材料,工作频率为27.12MHz。实验结果表明,在20W电功率的驱动下,对于2.7μm的光波长,衍射效率达55%,光透过率高于99%。该文还考虑了吸声和散热的问题,设计和制作了一套水冷散热机制,实验证明效果良好。The design, fabrication and applications of the 2.7μm acousto optic Q switch have been introduced in that the diffraction efficiency of the Q switch is up to 55% and the light transmittance is greater than 99% with respect to the laser wavelength of 2.7 μm at the driving power of 20 W. The sound absorption and heat radiation have been considered in the Q switch design. A water cooling mechanism has been designed and fabricated. The experiment verifies that the mechanism has good performance.
