Abstract : The invention comprises a semiconductor laser having an attached etalon which imposes two additional reflective cavity resonance conditions on a laser diode. The etalon has partially reflective front surface an an inner surface which act in conjunction with the internal cavity of the laser diode to reduce side mode emission from the laser. This results in laser emission of a single dominant mode, i.e., a single discrete wavelength of coherent light, from surface. Patents. (JHD)
