Laser with grating feedback unstable resonator |
摘要 |
A laser is disclosed which uses a curved spatial grating in either its reflective or output regions, or both, or distributed throughout the laser resonator, to produce an unstable optical reflection pattern which fills the resonating cavity more efficiently than in prior devices. Various combinations of different grating curvatures are disclosed. The invention is particularly adapted to semiconductor lasers.
