LASER ARRANGEMENT WITH AT LEAST ONE LASER RESONATOR COUPLED WITH A PASSIVE RESONATOR

摘要

a laser oscillator (11) and a passive resonator (7, 22) are longitudinally coupled so as to prevent multiple reflections inside the laser (11). the passive resonator (7, 22) is, for example, in stone incorporated into the laser (11).in the layered structure (5) of the semiconductor layer, an active layer (1), a laser layer, waveguide (2) transparent to the laser radiation are arranged with a gap between the two, no optical coupling occurs through the semiconductor material located in the e two.the layered structure (5) of semiconductor layers has a cavity (7) perpendicular to the direction of stratification and the direction of propagation of the light, which includes a vertical side surface (71) which forms a joint reflection of the laser oscillator (11) and passive (7, 22).and an inclined flank (72) which is outside of the layered structure (5) is not coupled to the waveguide layer (22) forming part of the resonator.
