A frequency-type optically controllable YAG:Nd(3+) laser
Abstract
The paper demonstrates the feasibility of using MOS-LC modulators based on the s-effect with an internal dividing mirror as the optically controllable mirrors of frequency-type YAG:Nd(3+) lasers. It is shown that the maximum energy of the laser in free-runnig operation of 10 mJ/sq cm is limited by the radiation resistance (not greater than 70 mJ/sq cm) of the orienting fluid, i.e., polyvinyl alcohol. The optical inhomogeneity of the modulator amounts to 20-40 percent, which is connected with the presence of a bonded single-crystal GaAs layer. The working frequency of the laser was about 20 Hz.
