Simultaneous tri-wavelength laser operation at 916, 1086, and 1089 nm of diode-pumped Nd:LuVO4crystal

“…Chen et al demonstrated a simultaneous cw tri-wavelength Nd:YAG laser at 1064, 1319, and 1338 nm [23]. Recently, we reported a simultaneous cw tri-wavelength Nd:YAG laser operating at 946, 1064, and 1319 nm [24] and a tri-wavelength Nd:YAG laser working at 1333.8, 1335, and 1338.2 nm [25]. Among these active media, neodymium-doped vanadate crystals are characterized by their high absorption and emission cross sections.…”

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].…”
