ABSTRACT:
A dynamically one-mode semiconductor laser having a laser diode with a coupled external resonator includes a resonator mirror disposed opposite a light emitting face of the laser diode and a collimation optics between the diode and the resonator mirror. The collimation optics includes a refractive hemispherical micro-lens having flat side applied to the resonator mirror which is manufactured by fusing a small drop of glass onto the resonator mirror.
