Abstract
A side-pumped solid laser employs diode array pumping to produce a near-diffraction-limited output beam in at least one dimension of the output beam, while maintaining high efficiency operation. Conversion efficiency is enhanced by orientation of a nonlinear crystal for enhanced beam quality along one axis, while improved beam quality is obtained in the other dimension by increasing absorption of the diode light within the laser crystal, reducing the crystal width, and/or a multi-pass reflector on the crystal face opposite the pumped face. The laser may be used in frequency doubling or wavelength shifting systems employing non-linear optical media. In that case, the output beam has its good axis preferentially aligned to enhance stability or prevent walkoff.
