Laser-diode-pumped solid-state laser using index-guided type multi-transverse mode broad area laser.

摘要

A laser-diode-pumped solid-state laser in which a solid-state laser crystal (13) is pumped by a laser beam emitted from a laser diode (11). An index-guided type multi-transverse mode broad area laser (11) having a single optical waveguide is used as the laser diode. This leads to reduced output variations and noise of the laser. Preferably, the front reflectivity of the laser (11) with respect to the oscillation wavelength of the same should be more than 20%.
