Abstract
A butt-coupling pumped single-mode solid-state laser is provided for generating a laser of single-transverse and single-longitudinal mode. The butt-coupling pumped single-mode solid-state laser includes: (1) a laser diode having an output facet for producing a pumping light; (2) a laser crystal immediately connected to the output facet of the laser diode with a specific length therebetween for generating an excited light at a fundamental wavelength in response to the pumping light; and (3) a mirror disposed away from the laser crystal with a specific distance for emanating a laser output.
