Abstract
The growth, spectroscopic properties, laser parameters, and laser performance of a Nd3+/Mg2+ co-doped congruent LiTaO3 crystal were investigated. Continuous-wave (cw) laser operation at a wavelength of about 1083 nm with a slope efficiency of nearly 12% was achieved. The maximum cw output power obtained was 615 mW, which, to the best of our knowledge, is the highest output power obtained for this crystal thus far. We propose that Nd:MgO:LiTaO3 lasers could be an excellent source for the optical pumping of helium, and may achieve second harmonic generation and optical parametric oscillation in the same crystal.
