Passive Q-switching performance with Co:LMA crystal in a diode-pumped Nd:LuVO4 laser

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].…”

LD end pumped mode locked and cavity dumped Nd:YAP laser at 1.34μm

“…Therefore, pulsed laser operation at a wavelength of 1.34 μm has attracted much attention in the last few years. Many laser materials including Nd:KGW [7], Nd:YAG [8], Nd:YAP [9], Nd:GdVO 4 [10][11][12][13][14], Nd:LuVO 4 [15], and Nd:YVO 4 [16][17][18][19][20], have been successfully used for pulsed 1.34 μm radiation. Due to the large stimulated emission cross section (2.2 × 10 − 19 cm 2 ), broad emission bandwidth (690 GHz) and high thermal conductivity (11 Wm − 1 K − 1 ), Nd:YAP is considered to be a promising laser crystal material for the pulsed radiation at 1.34 μm.…”

“…Up to now, several saturable absorbers such as Co 2+ -doped crystals [11,14,15,20], semiconductor saturable absorber mirrors (SESAMs) [17], nanotube saturable absorber [13] and V 3+ -doped crystals [7,8,10,12,18] have been employed as passive Q switches. The reported experimental results show that pulse widths obtained by Co-doped crystals such as Co:LMA are usually large [14,15], while a SESAM introduces higher loss and results in a lower damage threshold, which limits its application [17]. Among the V 3+ -doped crystals, V 3+ :YAG crystals have attracted great interest due to their excellent physical and optical performance at 1.34 μm.…”

Passively Q-switched intracavity frequency-doubled Nd:LuVO4/LBO green laser with a Cr4+:YAG saturable absorber

“…In a passively Q switched Nd doped laser, various saturable absorbers, such as Cr 4+ :YAG [8], V:YAG [21], GaAs [22], Co:LMA [23], and carbon nanotube [24], were used for the different emission wavelengths. In this work, a passively Q switched green Nd:LuVO 4 laser with a intracavity frequency doubling LBO crystal and a Cr 4+ :YAG saturable absorber was demon strated.…”
