摘要

采用波长为10.6μm的碲镉汞红外探测器测量了高功率CO2激光器(k-500, Coherent, Inc.)产生的表面温度上升时间。上升时间为72μs,不超过给定最大值90μs。此外,还研究了高功率CO2激光器的输出性能,即改变输出脉冲的占空比可以显著改变激光器的平均输出功率。不确定度在给定范围内(<±8%)。关键词:co2激光器,上升时间,输出功率,占空比

Measurement on the Performance of the CO2 Laser Applied to Dynamic Calibration of Surface Temperature Sensor
The rise time of surface temperature produced by high-power CO2 Laser (k-500, manufactured by Coherent, Inc.) is measured by Tellurium-cadmium-mercury infrared detector which responds sensitively to the laser with wave-length 10.6μm. The rise time is 72μs, not more than the given maximum 90μs. Moreover, the output performance of high-power CO2 Laser is also investigated, that is: changing the duty cycle of output pulse can change significantly average output power of the laser. The uncertainty is within the given scope (<±8%). Keywords-CO2 laser, rise time, output power, duty cycle
