Two novel applications of laser frequency splitting technology are reported, including two methods in solving the problem of mode competition to obtain a dual frequency laser whose frequency difference can cover 1-40 MHz, as well as the principle and the experiments of making a birefringence dual frequency laser itself be a displacement sensor.
主要介绍了激光频率分裂技术的两种新应用,包括用两种方法克服强模竞争以获得频差可覆盖1-40 MHz的双频激光器,以及将一个双折射双频激光器本身用作一个位移传感器,这种双频激光器可以填补塞曼激光器和双折射激光器之间存在的3-40 MHz频差空白,可以用作激光干涉仪理想的光源,位移传感器结构简单,其分辨率为79 nm,测量范围达到了15 mm,并且可以自校准。
When a dual-frequency laser is used as the light source of the ADI system, it requires that the synthetic wavelength be as small as possible, namely, the frequency-difference be as large as possible so as to improve the measurement accuracy.
大频差双频激光器在绝对距离干涉测量领域有着广泛的应用,因为这种测量方法测量的是距离而不是位移,所以不需要精密的导轨。
Because this measurement approach measures the distance rather than the displacement, it doesn’t need precise guide rail, but in order to improve the accuracy of absolute-distance measurement, smaller synthetic wavelength is required, which can be obtained by use of a dual-frequency laser source with its frequency-difference as large as possible.
双频激光器在绝对距离干涉测量中占有极其重要的地位,因为这种测量方法测量的是距离而不是位移,所以不需要精密的导轨,但要求双频激光光源的频差尽可能大,以获得较小的合成波长,进而提高测量精度。
The dual-frequency laser as a light source takes a key element in the interferometer.
其中作为光源的双频激光器在整个干涉系统中起着非常重要的作用。
