WebApr 1, 2011 · Misalignment of a laser cavity would increase the diffraction loss of the resonator, thus the resultant output power and beam quality would be degraded. In order to maintain sufficient output power and beam quality, it is very important to guarantee fine alignment of the cavity mirrors. WebIt is found that for linear misalignment given to any mirror of optical cavity, the angular misalignment exists and vice versa. Thus artifact elimination of laser cavity is sensitive process. With three piezo actuator based special mirror holders, a precise measurement of laser absorption can be done.
