摘要
研制了80mm开口的玻璃体吸收卡计,该卡计用于高功率脉冲激光能量的绝对测量,对卡计的主要性能进行了测试研究。结果表明,线性和重复性小于±1.5%。采用自动热平衡补偿技术,使卡计的“零漂”小两个量级,能量探测率提高20倍,测量周期缩短到1分钟以内。
Absorbing glass volume calorimeter for 80mm aperture has been fabrited. It is used for the absolute measurement of energy for high power pulsed lasers. Major performances of the ,alaorimeter have been measured. It is shown that linearity and repeatability are a less than±+1.5%. Applied automatic thermal balance compensation teehnique.thermalu "Zero drift" is reduced two orders of magnitude, and energy detectivity increases 20 times, and the measurement period reduced to a minute.
