【摘要】 <正>研制成用于实验室通用性较大的宽量程高功率脉冲激光体吸收卡计（LCB型）:吸光器由椭圆形（及圆形）中性有色玻璃AB₁₀（0.5毫米厚）与0.1毫米厚氧化黑铝片胶合而成,中间绕有φ0.04毫米锰铜电加热丝（模拟φ10毫米光斑）,可进行电能绝对定标.卡计配装最大通光口径φ45毫米（中空φ15毫米）聚光透镜（利用焦前测量,现镀1.06微米增透膜）及回收光装置.探测元件为0.1毫米镍铬-康铜（及考铜）热电偶,分别由26～40对组成,冷热端由尼龙垫圈隔开.更多还原

【Abstract】 In this paper the principle, configuration, behaviour and error analysis of the bulk absorption calorimeter which has large measurement range for ps pulsed laser radiation are reported. The measured energy ranges from 2 mj to 20 j, the operating wavelength ranges from 0.3m to 2m and 4m to 10m, the cooling time constant is about 73~75sec., and the accuracy of measurement is 5%更多还原
