Abstract
One of the present tasks in high-power solid-state laser development is to increase the beam quality. For 1.06 micrometer Nd:YAG lasers with unstable resonators, superGaussian outcoupling mirror can be used to obtain a high central intensity peak. Still, it contains less than half the power. Part of the rest should be focusable if bifocusing is avoided by birefringence compensation. If used with stable resonators, graded reflectivity mirrors were able to reduce the maximum beam parameter product from 16 to 10 mm*mrad. The maximum output power of 360 W remained unchanged. For 1.44 micrometer Nd:YAG lasers, which are used in laser medicine, apodized gratings have to be used instead of gradient mirrors. Preliminary investigations and first results are presented
