Mode - matching or modes adaptation system for laser with continuous tuning of grid external resonator

摘要

Modes adaptation system for laser with continuous tuning of grid an external resonator, which comprises:a laser resonator, which has a set of initially - laser - resonator modes, which the gain of irregularly spaced beam frequencies favors;a coupling resonator with a fixed length, which is coupled to the laser resonator and having a set of feedback - resonator modes, which the feedback of a plurality of uniformly spaced beam frequencies to the laser resonator is promoted; andan optical, non-linear path lengths - adjusting member, which the frequencies of the laser resonator modes changed, in order to selected frequencies to be adapted to the feedback - resonator modes.
