Abstract
For thermal lensing compensation of a Nd:YAG rod, placed in different positive-branch unstable resonators with super-Gaussian reflectivity p rofile of the output mirror, a deformable thin glass plate was used as the rear mirror. Unstable resonators with magnifications of M=1.5 and M=1.8 were designed for 0.8 mm . mrad value of the beam quality. For unloaded resonators the output energies of a laser working at 10 Hz re petition rate and pump energies up to 50 J per pulse were close to tho se obtained for 1 Hz repetition rate.
