ABSTRACT:
A high-powered diffraction limited diode pumped solid-state source optically end pumps a compact, widely tunable solid state material. Imaging of the collimated pump beam into the tunable medium produces ideal volumetric overlap producing high conversion efficiencies. Fully integrated pump source provides pump energy at or near the peak absorption wavelength. Birefringent elements placed intracavity are used for linewidth narrowing and tuning of the laser wavelength. Tunable active medium is placed in linear cavity arrangement utilizing a confocal or hemispherical arrangement. Mode waist is minimized in crystal such that there is optimal overlap with pump source while simultaneously maximizing extraction efficiency.
