ABSTRACT:
A high power laser resonator with improved efficiency of the lasing mechanism, for outputting a laser beam (6) of improved geometric and quality factors characteristics, adapted to the specific needs of high-speed-high-power laser material processing. In particular, conditions for output laser beam (6) geometric dimensions Dx, Dy, and corresponding quality factors, Kx, Ky, are set, such that the laser beam could be usable directly from the output of the resonator without adding beam shaping optics, and such that a better optimization of the extraction efficiency of laser power can be achieved. These four factors are in specific relationship with the wavelength of the laser radiation and the output laser power.
