摘要: 提高谐振腔的稳定性一直是激光技术的一个重大问题。将“猫眼”逆向器作为反射镜,组成“猫眼”谐振腔可提高激光谐振腔的稳定性。以功率稳定性为参考指标,做了一系列对比实验来对比“猫眼”谐振腔He-Ne激光器和现有He-Ne激光器在失调特性、温度漂移方面的性能。结果表明,“猫眼”谐振腔激光器稳定性显著优于传统平凹谐振腔和凹凹谐振腔激光器。进行了免调节“猫眼”谐振腔He-Ne激光器的实验,“猫眼”谐振腔He-Ne激光器的功率稳定性达到了以前各种构造的He-Ne激光器无法达到的高水平。Abstract: Laser cavity stability is a conventional and concerning subject from the birth of laser.With a "cat's eye" reflector as the reflecting mirror,the problems of laser adjustment and power stability can be solved.Comprehensive experiments are carried out in a half-external cavity He-Ne laser and the "cat's eye" reflector cavity,plane-concave mirror cavity and concave-concave mirror cavity.The results show that the use of the half-external "cat's eye" cavity can improve the laser stability and lower the power drift significantly.The adjustment problem is also considered and solved.A stable and adjustment-free He-Ne laser is finally realized,which exhibits remarkable advantages than the current He-Ne lasers.
