Optically pumped semiconductor laser

摘要

An optically pumped semiconductor laser and an optical pumping method are disclosed. The optically pumped semiconductor laser includes first and second reflective bodies forming a resonant region therebetween, a gain medium disposed between the first and second reflective bodies; and a light source for applying a source light to the resonant region in a lateral direction with regard to the gain medium for generating a basic wavelength. The laser further comprising an output mirror and a nonlinear crystal disposed between the output mirror and the second reflective body to generate a predetermined wavelength as a second harmonic of the basic wavelength.
