Abstract
An ultra compact monolithic crystal assembly (MCA) producing greater than 10 mw of coherent blue light at 473 nm is described. The MCA is comprised of Nd:YAG and off-axis cut KNbO3 crystal etalons, bonded together to form a flat and parallel optical cavity only 3 mm thick. Narrow-band HR coatings centered near 946 nm are applied to the exterior surfaces of the assembly, permitting 946 nm oscillation while suppressing competing 1064 and 1320 nm laser action. The KNbO3 crystal is cut for critically phase matched SHG (946/473) at approximately 35 degrees C. Using a commercially available 808 nm laser diode pump source, greater than 10 mw of blue light is obtained. Merits of this blue light emitting MCA are discussed.
