High quality mixed vanadate monocrystals Nd:Gd 0.7 Y 0.3 VO 4 with dimensions up to ∅ 25х70 mm and Nd ions concentration of 0.5% were grown. Diode pumped laser based on this crystal demonstrates lasing with output power up to 9.8 W at wavelength 1063.6 nm with slope and total efficiencies 66% and 64%, respectively. Thermooptical characteristics of this mixed vanadate crystal and Nd:GdVO 4 crystal were directly measured and compared.

“…Laser-diode (LD)-pumped all solid state pulse lasers have wide applications in the fields of remote sensing, medical treatment, coherent telecommunications and scientific research, because of their high conversion efficiency, compact structure and high beam quality. The neodymium-doped vanadate crystals have been demonstrated to be excellent materials for all solid state laser use-especially the Nd-doped mixed vanadate crystals, because of their enhanced energy storage capability compared to the single vanadate crystals; examples include Nd:Gd x Lu 1−x VO 4 [1,2], Nd:Gd x Y 1−x VO 4 [3][4][5][6] and Nd:Lu x Y 1−x VO 4 [7,8] crystals. On the other hand, crystals cut along the c axes were identified as having much better pulsed laser performance than the a-cut crystals, because of their much smaller emission cross section.…”

The continuous wave and pulsed laser performances of a laser-diode-end-pumped c-cut Nd:Lu 0.1 Y 0.9 VO 4 crystal have been demonstrated for the first time. The small emission cross section and appropriate upper level lifetime result in the c-cut Nd:Lu 0.1 Y 0.9 VO 4 crystals having excellent pulsed laser performance. When the pulse repetition rate was 6.4 kHz, the shortest pulse width, the largest pulse energy and the highest peak power were found to be 1.9 ns, 104.7 µJ and 55.1 kW, respectively, using a Cr 4+ :YAG crystal as the saturable absorber. These results were much better than those for an a-cut Nd:Lu 0.1 Y 0.9 VO 4 crystal under the same conditions.

“…Recently vanadate crystals have become widely used in diode-pumped lasers. In many papers, it has been shown (see, for example, [1][2][3][4][5][6]) that vanadate GdVO4, YVO 4 etc. crystals doped with rare earth elements, in particular Nd 3+ , are quite promising media for designing laser sources in the near IR range of the spectrum, including lasers based on the stimulated Raman scattering (SRS) effect for different purposes.…”

Nonlinear refractive index of vanadate crystals in the near IR region

2012

We used the single-beam Z-scan method, employing picosecond laser pulses with λ = 1064 nm, to measure the nonlinear refractive index and nonlinear absorption in vanadate crystals, which are promising for design of laser sources. We have established that there is practically no nonlinear absorption in these crystals in the near IR range and that doping them with neodymium ions leads to a significant reduction in the nonlinear refraction. This effect can be used to partially compensate for the negative impact of nonlinear refraction on the lasing characteristics of lasers.
