摘要
针对几种常见波段脉冲激光发射机所发出的脉冲激光波长、功率和宽度等特点,进行了激光峰值功率参数的综合测试技术研究。采用多波段光电探测和集成化组合式光学设计及先进的电路设计技术,并利用自行开发的信号通道和量程及采样频率可控的通用测试平台,对不同波长,选择了相应灵敏度高的探测器;对不同功率量程范围选择了合适的衰减片;并对宽度较窄的激光脉冲设计了合适的展宽放大和快速放电电路。实验结果表明:这项技术是实现多波段脉冲激光峰值功率综合测试的有效方法,具有良好的推广应用前景。
The comprehensive test technology for laser peak power parameter is investigated based on the characteristics of wavelength, power, and pulse width of pulse laser transmitted from laser transmitting sets operating in several common wavebands. Utilizing the selfdeveloped universal test platform, the corresponding high sensitivity detectors are selected for different wavelengths, suitable attenuating plates are adopted for different power ranges, and the proper widening magnifications and fast discharge circuits are designed for narrower laser pulses with the advanced technology of multiband optronic detection, integrated assembled optical design and circuit design. Experimental results indicate that the technology is an effective way to implement the comprehensive test of the multiband laser peak power.
