ABSTRACT:
A high-power semiconductor diode laser or array of semiconductor diode lasers (14) optically end-pumps a compact, tunable, solid-state laser (28) with a pumping beam (74) well-matched to the absorption bandwidth and mode volume (78) of the solid-state laser (28). Tilted birefringent plates (210) positioned within the solid-state resonator cavity (16) are employed to control the spectral bandwidth and wavelength output of the waveguide pumping beam (204). Infrared output (100) generated by such a solid-state laser (28) is coupled into a nonlinear waveguide (200) and converted to visible output (206) through the process of second-harmonic generation.
