ABSTRACT:
A laser apparatus for nonlinear conversion of light is disclosed utilizing a laser diode having a reflective back facet and a front facet having a reflectance of less than about 1% for emitting a multifrequency optical beam, and a nonlinear optical element for receiving the multifrequency optical beam and for generating a frequency-converted radiation. An external frequency-selective reflector is provided for power and spectral stabilization of the multifrequency optical beam, and for confining its optical spectrum within a bandwidth of efficient nonlinear conversion in the nonlinear optical element. The laser diode reflective back facet and the external frequency-selective reflector form an extended laser cavity. In operation, the multifrequency optical beam contains a plurality of longitudinal modes of the extended laser cavity which are confined within the frequency conversion bandwidth of the nonlinear element. The external frequency-selective reflector may comprise a waveguiding element such as a single-mode fiber incorporating a Bragg grating, and may also comprise a Fabry-Perot etalon.
