Abstract： |
A displacement self ¨C sensing Ne ¨C He laser system of cat eye folding cavity is featured as not using cat eye inversing apparatus as cavity lens of resonant cavity but using it as refracting ¨C reflecting apparatus of light to refract ¨C reflect light outgoing from capillary of semi ¨C external cavity Ne ¨C He laser gain tube onto reflector or total reflection film fixed on system statically in parallel to output lens for forming complete resonant cavity structure to be folding cavity structure i.e. utilizing output lens at one end of gain tube and said reflector or total reflection film as two cavity lens of laser resonant cavity . |
