摘要
Nd∶YAG激光回馈干涉仪已实现仪器化,但在实际应用中仍然存在不足。测量了Nd∶YAG微片激光器的基本参数,设计了红光指示装置、准直扩束装置和空气折射率补偿系统,完成了指示1064nm的不可见光的同时实现了量程提高和波长补偿,得到了使用更方便、量程更大、应用范围更广、测量精度更高的实用Nd∶YAG激光回馈干涉仪。
At present, Nd.＇YAG laser feedback interferometer has been achieved. However, in the actual application some deficiencies still exist in this system. Basic parameters of Nd： YAG microchip laser are measured and the instruction of the invisible light with the wavelength of 1064 nm is realized, with the improvement of the measurement range and the compensation of air refractive index, by combining red indicating device, collimating and beam expanding device and the refractive index of air compensating system with the original Nd： YAG laser feedback interferometer. So Nd：YAG laser feedback interferometer is more convenient to use with a broader application and higher accuracy.
