摘　　要：为了满足光束合成、激光对抗、材料激光损伤测试等领域的激光功率测试需求,研制了一种基于赛贝克效应的百瓦量级热电堆激光功率测试仪器。该仪器无需偏置电压电路即可正常工作,能够实现连续激光辐射功率测试且探测的激光功率量程宽、稳定性高。对波长为1064 nm的激光功率进行了测试实验。在1.5~250 W的功率范围内,采用本文方案研制的热电堆激光功率计的测试结果与标准激光功率计测试结果之间的误差在±3%范围以内。In order to meet the requirements of laser power measurement in the fields of beam synthesis,laser countermeasure and laser damage measurement of materials,a hundred-Watt-level thermopile laser power measurement instrument based on the Seebeck effect is developed.This instrument can work normally without bias voltage circuit,and can realize the continuous laser radiation power measurement with wide range and high stability.The power of the laser with the wavelength of 1064 nm is tested.In the power range of 1.5--250 W,the error between the test results of the thermo reactor laser power meter developed in this paper and that of the standard laser power meter is within the range of±3%.
