High-power efficient tunable Nd:GdVO_4 laser at 1083 nm

Abstract

An efficient tunable diode-pumped Nd:GdVO4 laser at 1083 nm has been constructed by suppressing the higher gain transition near 1063 nm. With 12.5 W diode pump power, the free-running output power centered about 1083 nm was up to 3.4 W, corresponding to an optical-to-optical conversion efficiency of 30.1%. When a simple uncoated etalon was used as a wavelength-selective element, the output power at each helium transition was higher than 2.5 W.

Highly efficient TEM 00 mode LD-pumping 1063nm Nd:GdVO 4 laser with short cavity

“…The maximum output laser power is 2.05 W when the pump power is 3.76 W, corresponding to an optical-to-optical conversion efficiency of 55% and a slope-efficiency of 70%. Such a slopeefficiency is much higher than those of the reported lasers who used traditional Nd:GdVO 4 bulk crystals pumped by 808 nm LD [1][2][3][4][5][6] . Comparatively, the slope-efficiency is comparable to the results(71 %) obtained with a component Nd:GdVO 4 crystal reported by Xudong Li [7] and the results(78 %) obtained with 879 nm LD direct pumping Nd:GdVO 4 crystal reported by Takayo Ogawa [8] .…”

“…Based on the outstanding characteristics of Nd:GdVO 4 , various wavelength lasers from blue to visible light to infrared have been studied widely and many excellent experimental results have been obtained [3][4][5][6] . In this paper, a highly efficient 1063 nm Nd:GdVO 4 laser has been demonstrated.…”

Diode-pumped Pr3+:LiYF4 visible dual-wavelength laser

“…So far, dual-wavelength laser for different transitions of Nd 3 þ have been reported for some crystals such as Nd:YAG [6][7][8][9][10][11][12][13][14][15][16][17][18], Nd:YVO 4 [19][20][21][22][23][24][25][26], Nd:GdVO 4 [27][28][29][30][31], Nd:LuVO 4 [32,33], Nd:YAlO 3 [34][35][36][37] Nd:GSAG [38], Nd:LSO [39], Nd:LYSO [40,41], Nd:SYSO [42] and Nd:YAB [43]. However, few researches on dual-wavelength Nd 3 þ -doped lasers in the visible spectral region have been reported [44][45][46].…”

Crystal growth and laser performance of neodymium-doped scandium orthovanadate

“…These advantages simplify wavelength tuning and pump beam collimating requirements for diode pumping [12][13][14]. As an isomorph of YVO 4 , GdVO 4 is also an excellent Nd-laser host due to similar properties and a thermal conductivity comparable to that of YAG [15][16][17][18]. In recent years, another Nd-doped rare-earth orthovanadate, Nd:LuVO 4 , has been investigated.…”
