Compact stable passively Q-switched Nd:YVO4 laser with tungsten disulfide saturable absorber

Q‐switched Nd:YVO4 laser with TiS2 saturable absorber

“…Recently, graphene‐like two‐dimensional (2D) materials attracted the attention of researchers 15–18 . According to previous works, many 2D materials were used as SAs in fiber and solid‐state lasers 19–30 . TiS 2 is a new 2D material with appropriate modulation depth, high damage threshold, and high stability, but there are few reports of TiS 2 SA in fiber and solid‐state lasers 31,32 …”

“…[15][16][17][18] According to previous works, many 2D materials were used as SAs in fiber and solid-state lasers. [19][20][21][22][23][24][25][26][27][28][29][30] TiS 2 is a new 2D material with appropriate modulation depth, high damage threshold, and high stability, but there are few reports of TiS 2 SA in fiber and solid-state lasers. 31,32 In this paper, the liquid-phase ultrasonic stripping preparation method was used to fabricate TiS 2 SA, and a Q-switched Nd:YVO 4 laser was demonstrated by using the TiS 2 SA.…”
