摘要
A laser-resonator includes a praseodymium-doped crystal gain-medium optically pumped by plane-polarized blue light delivered by a frequency-doubled, external cavity, surface-emitting semiconductor laser. The laser-resonator generates fundamental radiation at one of several possible wavelengths between about 500 nm and 750 nm. The fundamental wavelength generated is determined by a wavelength-selective element located in the laser-resonator and the polarization-orientation of the blue light relative to the c-axis of the crystal gain medium. An optically nonlinear crystal located in the laser-resonator frequency doubles the fundamental radiation to provide ultraviolet radiation.
