The cryogenic deuterium-tritium targets are very important to laser inertial confinement fusion, and mainly adopts plastics capsule, Be shell, foam shell etc.
低温冷冻氘氚靶对于惯性约束聚变研究至关重要，主要有塑料微球靶、金属铍球靶、泡沫球壳靶等。
Firstly, the laser power was measured by cryogenic radiometer in visible and near infrared spectral regions (488~944 nm), uncertainty of power measurement is less than 0.016%.
首先低温辐射计采用电替代方法测量单个波长激光绝对光功率，测量不确定度低于0.016%。
The results of comparison indicate that the laser power measure uncertainty of cryogenic radiometer of 2003 year is less than that of 1999 year;
