Design and application of a single-mode Nd:YAG laser with self-pumped phase conjugation in laser crystals and saturable absorber

The repetitively pulsed Nd:YAG laser with dynamic cavity formed with participation of dynamic holographic gratings induced in Nd:YAG laser crystal and Li:F absorber has been investigated. The generation regimes and technological opportunities of this Nd:YAG laser were studied. High spatial brightness of radiation at diffraction limited divergence has allowed to carry out effective punching of calibrate holes in different materials with a diameter up to 15 micrometers and maximal depth up to 20 mm.
