摘要： 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.

摘要： An apparatus for converting an input optical serial data pulse stream into output optical parallel pulse streams comprises a waveguide that provides optical parallel pulse streams resulting from second-harmonic radiation generated by colliding a timing pulse against each data pulse of an optical serial data pulse stream input into the waveguide. The waveguide comprises a first reflector positioned at a location substantially opposing the waveguide's output. The first reflector reflects substantially all of the component of the second-harmonic radiation propagating in a direction away from the waveguide's output. The waveguide further comprises a second reflector opposing the first reflector and positioned between the first reflector and the waveguide's output to selectively reflect a portion of the component of the second-harmonic radiation propagating in a direction toward the waveguide's output.

摘要： A high-power unstable resonator semiconductor laser (14) emits optical output of greater than 50 mW in a wavelength range of 700-1100 nm. A grating (116,136) may be positioned external to URSL (14) to control the spectral bandwidth and wavelength output of the waveguide pumping beam (74). Alternatively, URSL (14) may be fabricated with a distributed feedback (DFB) grating or a distributed Bragg reflector (DBR). Infrared waveguide pumping beam (74) generated by such a high-power unstable resonator semiconductor laser (14) is coupled into a nonlinear waveguide (28) and converted to visible or near ultraviolet output (100) through the process of second-harmonic generation.
