Abstract
An end pumped solid-state laser is comprised of a resonator formed of a pair of mirrors and a laser rod disposed between the pair of mirrors, an exciting light source for generating a pumping light which excites the laser rod and a converging optical element for converging the pumping light from the exciting light source so that the converged pumping light is irradiated on an end face of the laser rod. The wavelength of the light generated from the exciting light source is widened in band and/or a converging optical element having a large wavelength dispersion is employed, whereby heat generation in the optical axis direction of the laser rod is uniformed so as to generate a laser beam of large power.
