| 摘 要： | 近年来,用光反馈实现半导体激光双稳态的研究十分活跃。在小型准各向同性(全内腔)He-Ne激光中,同样可以建立“双稳态”。这种“双稳态”的光反馈激光开关干涉仪可用来产生精密的位移位置信号。

| Abstract: | Feeding a polarized light beam back into a small quasi-isotropic He-Ne laser, a "Light Feed-back Polarized Flip-flop Laser Interforometer" is constructed. With the movement of the feed-back mirror, the polarization of the laser will flip-flop, and this square wave output is an accurate measurement of the displacement of the feed-back mirror. |
