Abstract
A continuous-wave dual-wavelength Yb:CALGO laser has been demonstrated using a 12-mm thick off-surface axis birefringent filter. The obtained wavelength spacing could be tuned from a few nm up to tens of nm. In the experiments ~7.5 W of output power was obtained for 25 W of the incident pump power.
