“…The input values for the numerical calculations performed for the 3% Nd 3+ doped LuVO 4 powder are the following: v = 2x10 8 m/s, σ em =1.46 x10 −19 cm 2 , L has been calculated using a filling factor of 60%, a transport length of l t = 6 µm, an absorption cross-section of 6.9x10 [19], K=17000 s −1 and β = 0.18 [20]. The pump pulse was simulated by the I in (t)=I 0 t exp(-α t) function with a time constant α=5x10 8 s −1 .…”

Room temperature random lasing action is demonstrated for the first time in a low concentrated neodymium doped vanadate crystal powder. Laser threshold and emission efficiency are comparable to the ones obtained in stoichiometric borate crystal powders. The present investigation provides a complete picture of the random lasing characteristics of Nd-doped vanadate powder both in the spectral and temporal domain, together with a simplified model which accounts for the most relevant features of the random laser. ©2011 Optical Society of America

“…Moreover, Nd:LuVO 4 crystal has a high damage threshold, and it is easy to process [19]. The research to output wavelengths involving 4 Nd:LuVO 4 crystals were mostly focused at 1066 nm [20][21][22][23][24][25][26][27][28][29] and 1343 nm [30]. However, in all these studies the pumping is made in levels above the emitting level 4 F 3/2 of Nd 3+ , usually in 4 F 5/2 .…”

We report a high-efficiency Nd:LuVO 4 laser operating at 1066 and 1343 nm, respectively, direct pumped by a diode laser at 880 nm. The maximum outputs of 10.5 and 7.0 W, at 1066 and 1343 nm, respectively, are obtained in a 8-mm-thick 0.4 at.% Nd:LuVO4 crystal with 16.9 W of absorbed pump power at 880 nm, leading to a high slope efficiency with respect to the absorbed pump power of 64.4 and 44.5%. Under traditional pumping at 809 nm, the maximum outputs of 9.8 and 6.2 W, at 1066 and 1343 nm respectively, are obtained with 19.3 W of absorbed pump power, corresponding to the slope efficiency with respect to the absorbed pump power of 54.9 and 34.9%.

This work presents experimental results concerning an actively Q switched intracavity frequency doubled Nd:LuVO 4 /LBO green laser with an acousto optic modulator operated at the wavelength of 0.53 μm. The green average output power of 2.8 W was obtained at a pump power of 16.3 W and a pulse rep etition rate of 20 kHz, resulting in an optical conversion efficiency of 17%. When the pulse repetition rate is operated at 5 kHz, the shortest pulse width and the highest peak power at 0.53 μm were measured to be 26.5 ns and 8.43 kW, respectively.
