摘 要: | 研究了铜在CO2激光辐照下达到热平衡时表面的温度涨落.发现铜在达到热平衡后,铜块表面温度出现涨落,涨落的最大幅度不随幅照时间而改变.同时,这一温度涨落也反映了国产HGL895型5kW横流连续CO2激光器功率稳定性的一些问题,对采用反馈电路稳定激光输出功率这一工艺有参考意义.

Abstract: | The temperature fluctuat ion of copper surface,which was in a the rmal equilibrium state under the irradia ted condition with a CW CO 2 laser,was c arefully measured.And the maximum range of the temperature fluctuation was no re lation to laser irradiation time.So the temperature fluctuation of the copper su rface showed considerably the laser powe r stability of 5kW CW transverse flow CO 2 laser.The result was useful to contro l the power stability of a CO 2 laser. |
