    摘要:

    该文介绍了应用于激光器系统中的微型声光调Q开关的设计、测试及应用。通过有限元数值分析各因素对声光调Q开关衍射损耗的影响,提出了一种新型优化声光调Q开关的设计方案。选用氧化碲(TeO2)晶体作为光电偏转材料,利用集成电路兼容工艺加工得到封装尺寸为17.8 mm×6.8 mm×17.8 mm,工作波长1 064 nm,光脉冲上升时间28.99 ns的微型声光调Q开关。该微型声光调Q开关具有优异的性能,其体积缩减到原来产品的40%;光孔径为0.8 mm;在全温范围(-45~70 ℃)内稳定工作,衍射损耗保持在35%(±2%)。

    Abstract:

    This paper introduced the design,testing and applications of micro acoustooptic Qswitch in laser system. The influences of various factors on the diffraction loss of the acoustooptic Qswitch was analyzed by the finite element method and a new design scheme for optimizing the acousticoptical Qswitched was proposed. The tellurium oxide (TeO2) crystal was selected as the photoelectric deflection material, and the micro acoustooptic Qswitch with a package size of 17.8 mm×6.8 mm×17.8 mm, operating wavelength of 1 064 nm and the light pulse rise time of 28.99 ns was fabricated by using the integrated circuit compatible process. The micro acoustooptic Qswitch has excellent performance, in which the volume has reduced to 40% of the original product and the diameter of the aperture was 0.8 mm. With stable operation over the full temperature range (-45~70 °C), the diffraction loss was maintained at 35% (±2%).
