Abstract
A diode pumped laser is wavelength converted using an intracavity non-linear optical crystal, and the wavelength converted output is passively stabilized by a short cavity using unpolarized laser output. End pumping limits the number of transverse cavity modes, and intracavity etalon effects may be achieved by additional coatings deposited upon the laser or non-linear crystals themselves, further reducing the longitudinal mode spectrum. Wavelength converted output is enhanced by minimizing backward conversion in a linear cavity, or by folding the cavity via an angled face of the non-linear or the laser crystal.
