| 摘 要： | 提出了双路Cr，Tm，Ho：YAG激光器的设计方案，通过单片机对激光电源和步进电机(间接控制电机带动的旋转全反镜)进行控制，实现轮流出光的两路激光器合光路输出。在单脉冲输入能量100J、重频20Hz情况下，激光器输出功率达到35．4w，光纤末端输出功率为22．7w，总的耦合效率为64％，而且此方案并不局限于同种波长激光的耦合。

| Abstract: | The Cr,Tm,Ho:YAG laser device was provided for co-axial positioning of two laser beams along a single axis.The output of each laser rod is combined in turn and interleaved into a single output beam by using a rotatable reflector.The rotary rate of the stepping motor and the pump currents of two lasers are controlled by a single chip microcomputer.The output power is 35.4 W and the end of fiber is 22.7 W when input pump energy is 100 J and repetition frequency is 20 Hz.The coupling efficiency is 64%.This method is not only suitable for the same wavelengths,but also suitable for two different wavelengths. |
