High-power visible laser sources were realized by using Nd-based media in thin-disk geometry. The optical pumping was performed with diode lasers at 0.81 mum. To the best of our knowledge, for the first time pumping at 0.88 mum into the 4F3/2 level was also employed for Nd-vanadates for such a scheme. Improved performance are expected by optimizing various parameters of the laser configuration and, especially for pumping into the 4F3/2 emitting level, by using a pump scheme with increased pump passes in the laser crystal.
