Abstract
When adjusting the resonator of a half-infracavity or an extracavity of gas lasers, a He—Ne laser beam was usually used. When the He—Ne laser beam is tuned-in the light-axis ofthe gas laser, a reflecting light from the Brewster window can be seen clearly. While if another visible laser light ( He—Ne light also good) is sent inversely along the path ofthe above reflecting lights this light can be sent into the resonator via the Brewster window. Thus, a light-probe is created for in situ monitoring the optical cavity. Practice showed that this method is especially useful for monitoring the cavity of diffraction-grating line-selection CO2 lasers.
