Method for emitting a pulsed laser beam and associated laser source

摘要

The method involves generating a laser pumping radiation with intensity (Jc) adapted to bring a crystal (5) to a laser emitting threshold, where the crystal is yttrium aluminum garnet (YAG), yttrium orthoaluminate (YALO), yttrium orthovanadate (YVO4) or yttrium lithium fluoride (YLF) crystal doped with thulium or holmium. Another laser pumping radiation with intensity (Jp) is generated in an echelon form, where the intensity of the latter radiation is higher than that of the former radiation, when the latter radiation is superimposing a part of the former radiation or a radiation next to it. An independent claim is also included for a laser source generating laser pulses.
