The continuous-wave passive mode-locking operation of a diode-pumped mixed Nd:Lu0.5Y0.5VO4 laser

Abstract

We reported a continuous-wave (CW) passively mode-locked Nd:Lu0.5Y0.5VO4 laser at 1064 nm. A partially reflective semiconductor saturable absorber mirror was exploited in the Z-typed resonator. The Nd:Lu 0.5 Y 0.5 VO 4 laser generated CW mode-locked pulses with an average output power of 860 mW, a repetition rate of 53.7 MHz, and a pulse duration of 8.7 ps.

Actively Q-switched laser performance comparison between Nd:Lu0.15Y0.85VO4 and Nd:Lu0.33Y0.37Gd0.3VO4 mixed crystals

“…In order to improve the performance of Q switched laser, the double mixed Nd:Gd x Y 1 -x VO 4 , Nd:Lu x Gd 1 -x VO 4 , and Nd:Lu x Y 1 -x VO 4 crystals were successfully grown [11][12][13][14][15][16][17]. Due to the inhomoge neous broadening in the fluorescence spectra, these double mixed crystals has much broader fluorescence line width than the single vanadate crystals such as Nd:GdVO 4 , Nd:YVO 4 , and Nd:LuVO 4 [18][19][20][21][22]. The passively mode locked Nd:Lu x Y 1 -x VO 4 laser with a semiconductor saturable absorber mirror (SESAM) and the passively Q switched Nd:Lu x Y 1 -x VO 4 laser with GaAs have been demonstrated [23,24].…”

Crystal growth, spectroscopic characterization and laser performance of Nd:Lu0.33Y0.36Gd0.3VO4 crystal

“…A 2.78 W average power with the shortest pulse width of 6.5 ns has been obtained from passively Q switched Nd:Gd 0.64 Y 0.36 VO 4 laser [1]. According to Huang et al a CW mode locked pulses with an average output power of 860 mW and a pulse duration of 8.7 ps has been generated by the Nd:Lu 0.5 Y 0.5 VO 4 laser [8]. Recently, the passively mode locked Nd:Lu 0.15 Y 0.85 VO 4 lasers and the pas sively Q switched Nd:Lu 0.15 Y 0.85 VO 4 lasers with differ ent saturable absorbers have been realized [9][10][11][12].…”

Actively Q-switched performance of a mixed crystal Nd:Lu0.5Y0.5VO4 at 1.34 μm

“…Neodymium (Nd) doped mixed vanadate crystals such as Nd:Gd x Y 1 -x VO 4 and Nd:Gd x Lu 1 -x VO 4 have drawn more interests in the fields of high peak power Q switching and mode locking lasers due to moderate stimulated emission cross section and larger fluores cence bandwidth [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Recently, a novel mixed crystal Nd:Lu x Y 1 -x VO 4 was grown by Fuzhou Univer sity and its continuous wave (CW) and Q switched operation at 1064 nm has been demonstrated success fully by our group.…”
