Study of LD pumped Q-switched Nd:Y0.5Lu0.5VO4 laser with acousto-optic modulator

Optical spectroscopy of Nd3+/Mg2+co-doped LiTaO3laser crystal

“…The RMS is very low with a value of 0.29 × 10 −20 cm 2 , which confirms the better consistency of our fitting, and thus the obtained results can be taken as reasonable. The value of 6 is relatively large, which indicates that this crystal exhibits relatively low viscosity and rigidity [16]. Moreover, the spectroscopic quality parameter 4 / 6 , which is equal to 0.66, is less than 1 and demonstrates that the emission from 4 F 3/2 to 4 I 11/2 is more feasible than to 4 I 9/2 [16].…”

“…In the field of crystalline lasers operating near 1000 nm, Nd-doped crystals have recently attracted much attention due to their possible utilization as efficient laser diode (LD) pumped solid-state lasers [5,6]. Interest in LT doped with Nd 3+ had grown significantly owing to its promising applications in integrated optoelectronics [7][8][9][10][11].…”

Diode-pumped actively Nd:Lu0.33Y0.37Gd0.3VO4 Q-switched laser with electro-optic (EO) modulator

“…The Nd-doped single van adate crystals are the commonly used Q switched laser gain media for the diode pumped Q switched lasers due to their broad absorption bandwidths, large absorp tion and emission cross sections as well as high chemical stability such as Nd:GdVO 4 [4], Nd:YVO 4 [5], and Nd:LuVO 4 [6][7][8]. In order to improve the performance of lasers, 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 have been grown and extensively studied as gain media for the Q switched lasers [9][10][11][12][13][14][15][16][17][18]. The experimental results show that shorter pulse width and higher peak power in the Q switched lasers with the double mixed crystals can be obtained than those with single vanadate crystal lasers because of the inhomoge neous broadening of the fluorescence line widths.…”
