ABSTRACT:
An conversion laser design for the generation of blue light incorporates fiber Bragg gratings, mode-matching fibers, pump noise reduction, pump combining, and a self-oscillating pumping scheme, allowing the use of a single wavelength pump laser to pump through a cross-relaxation method of Yb.sup.3+ to Pr.sup.3+, as well as a self-oscillating pumping method. The use of narrowband mirrors, such as FBGs, is also disclosed for the upconversion laser to allow suppression of parasitic oscillators.
