[Show abstract][Hide abstract] ABSTRACT: We report efficient laser emission on the 914 nm 4
3/2 to 4
9/2 transition in Nd:YVO4 under the pump with diode lasers at 888 nm for the first time. Continuous wave 6.57 W output power at 914 nm is obtained
from a V-type resonator under 18.3 W of absorbed pump power; the slope efficiency with respect to the absorbed pump power
was 60.6%. Moreover, intracavity frequency doubling with BiB3O6 (BiBO) nonlinear crystal yielded 1.77 W of deep-blue light at 457 nm with beam quality characterized by an M2 factor of 1.25.
[Show abstract][Hide abstract] ABSTRACT: We present for the first time a Nd:YVO4 laser emitting at 1064 nm intracavity pumped by a 916 nm diode-pumped Nd:LuVO4 laser. A 809 nm laser diode is used to pump the Nd:LuVO4 crystal emitting at 916 nm, a Nd:YVO4 laser crystal was pumped at 916 nm and lased at 1064 nm. Intracavity sum-frequency mixing at 916 and 1064 nm was then realized
in a LiB3O6 (LBO) crystal to reach the blue range. We obtained a continuous-wave output power of 216 mW at 492 nm under 19.6 W of incident
pump power at 809 nm.
[Show abstract][Hide abstract] ABSTRACT: We present for the first time a dual-wavelength laser operation at 1064 and 914 nm in two NdYVO4 crystals. A 879 nm laser diode is used to pump the first Nd:YVO4 crystal emitting at 914 nm, and the second Nd:YVO4 laser emitting at 1064 nm intracavity pumped at 914 nm. A total output power of 4.28 W at the two fundamental wavelengths
was achieved at the absorbed pump power of 13.8 W. The M2 values for 914 and 1064 nm lights at the maximum output power were found to be around 1.3 and 1.1, respectively.
