Diode-pumped acousto-optical Q-switched 912nm Nd:GdVO4 laser and extra-cavity frequency-doubling of 456nm deep-blue light emission

Passively Q-Switched Operation of a Tm,Ho:LuVO4 Laser with a Graphene Saturable Absorber

“…Vanadate crystals are of particular interest as a potential laser host material, because they are suitable for rare-earth ions doped or co-doped lasers, such as Nd:GdVO 4 , Nd:GdVO 4 , Tm,Ho:YVO 4 , Tm,Ho:GdVO 4 , Ho:LVO 4 and Tm,Ho:LuVO 4 [8,[19][20][21][22][23][24][25]. Nd:GdVO 4 and Nd:YVO 4 lasers have been demonstrated at 1 µm wavelength range [26,27]. Tm,Ho:YVO 4 and Tm,Ho:GdVO 4 have been used as the laser crystal in continuous wave (CW), PQS, and acousto-optically (AO) Q-switched mode operation, and PQS Tm,Ho:YVO 4 and Tm,Ho:GdVO 4 laser were demonstrated with an SA of a 2 mm-thick Cr:ZnS crystal with a pulse width of less than 100 ns and a pulse energy over 100 µJ [8,28].…”

Quasi-three-level Nd:GdYNbO4 927 nm laser under 879 nm laser diode pumping

“…Moreover, by frequency doubling blue lasers could be generated with many applications ranging from underwater communication, color displays, and biological diagnostics to optical data storage [6][7][8]. Since Fan and Byer demonstrated the first end-pumped Nd:YAG 946 nm laser in 1989 [9], plentiful investigations have been conducted on Nd 3+ -doped quasi-three-level lasers with different host materials [10][11][12][13][14][15][16].…”
