| 摘 要： | 本文的研究结果和现行的CO_2激光的稳频方法有较大不同,它只有一个P-P线对,不但有永久固定的线序(signature),而且可以在四个运转频率中快速地成对切换。此四个工作频率分属两个波长,每个波长的频率稳定度都在10~(10)量级,由四个工作频率形成的二级合成波长可达到米级。这对于无导轨的绝对距离干涉计量学极有意义。

| Abstract: | A dual- wavelength frequency stabilized CO2 laser with a wide band dispersion cavity is described. A sequence of four operating frequencies can be composed on only one P-P line pair. The signature in this multi-frequency CO2 laser is unvaried and permanent. The frequency stabilities of simultaneous oscillations are about several parts in 1010 (sample time 10 sec. ). |
