全内腔角块定频差双折射双频He-Ne激光器及其稳频研究

Full-inner-cavity Birefringence Dual-frequency He-Ne Laser with Fixed Frequency-difference by Angle-block and Frequency-stabilization

介绍了全内腔角块定频差双折射双频He Ne激光器的结构设计 ,用等光强法对其进行热伺服稳频 ,在 8h工作时间内 ,稳频精度在 2× 10 -7以上。

This paper discusses the design of full-inner-cavity birefringence dual-frequency He-Ne laser with fixed frequency-difference by angle-block structure, and the frequency-stabilization schemes of serving the laser with heater by equal light intensity methods. The accuracy of frequency stability is higher than 2×10-7 within 8 hours.
