摘要

为了满足连续激光的功率测量，针对其0.4μm至2.4μm宽波段、多路输出和甚高重复频率的特点，设计了一套专用的连续谱激光能量采集系统，能够对连续谱激光在上述波段范围内的能量分布进行高精度检测。系统选择以氧化铜作为热电堆吸收层的探测器，结合信号处理技术，通过加权滑动均值滤波的算法来实现了对宽光谱激光能量的动态响应与精确分辨。通过针对671nm和1064nm波段的光能校准，系统能够在复杂光谱条件下提供稳定的测量结果，实验结果表明，采用本文方案研制的激光功率测量系统的测试结果与标准激光功率计测试结果之间的误差在±1.5％范围以内。这一结果展现测量连续谱激光能量系统的可行性。

Abstract

To meet the requirements of continuous laser power measurement

a specialized energy collection system for continuous spectrum lasers is desighed

which is capable of high-precision detection of energy distribution in the wavelength range from 0.4μm to 2.4μm

with multiple output channels and extremely high repetition frequency. The system uses a thermopile detector with copper oxide as the absorption layer

combined with signal processing techniques

and implements dynamic response and precise resolution of wide-spectrum laser energy using a weighted sliding mean filter algorithm. Through energy calibration for the 671 nm and 1064 nm bands

the system can provide stable measurement results under complex spectral conditions. Experimental results show that the measurement error between the system developed using this approach and the standard laser power meter is within ±1.5%. This result demonstrates the feasibility of measuring a continuum laser energy system.
