A passively mode-locked Tm:YAG laser with a titanium disulfide saturable absorber

Passively Q‐switched Tm:YAG ceramic laser with TiS2 saturable absorber

“…Employing TiS 2 -SA, passively modelocking Tm:YAG laser was achieved at 2011.4 nm, an average output power of 102 mW and a pulse duration of 224 ps were obtained. 30 In this work, a highly efficient large-area 2D titanium disulfide nanosheet film is manufactured as a saturable absorber. Moreover, the saturable absorption characteristic of TiS 2 is certified by the open-aperture Z-scan technology at the 2.0-micron.…”

“…Based on its nonlinear absorption properties, 29 TiS 2 has been further investigated and employed as SAs from the visible to infrared (IR) range. Employing TiS 2 ‐SA, passively mode‐locking Tm:YAG laser was achieved at 2011.4 nm, an average output power of 102 mW and a pulse duration of 224 ps were obtained 30 …”

Operation of a passively mode‐locked Tm:YAG laser with tantalum aluminum carbide as a saturable absorber

“…12 The novel emergence of 2D materials such as graphene, black phosphate (BP), boron nitride (BN), transition metal disulfide (TMDC), and others have recently attracted remarkable research and been extensively investigated for ultra-short lasers in 1-3 µm. [13][14][15][16][17][18][19][20][21][22] However, among the 2D materials, graphene, BP, and BN have some shortcomings, for example, lower absorption efficiency and rapid oxidation. [23][24][25] Recently, MXene materials have been researched to replace some conventional SAs.…”

“…Two‐dimensional (2D) materials show high performance in nonlinear optical and optoelectronic properties and significant advantages in chemistry, condensed matter physics, material science, and nanotechnology which make them suitable as SA in pulse laser systems 12 . The novel emergence of 2D materials such as graphene, black phosphate (BP), boron nitride (BN), transition metal disulfide (TMDC), and others have recently attracted remarkable research and been extensively investigated for ultra‐short lasers in 1–3 µm 13–22 . However, among the 2D materials, graphene, BP, and BN have some shortcomings, for example, lower absorption efficiency and rapid oxidation 23–25 .…”
