“…Chen's group realized graphene/WS 2 vdW heterostructure Q‐switching waveguide lasers operating at 1064 nm, and the shortest pulse width was determined to be 117 ns . Tu's group demonstrated a dual‐wavelength passively Q‐switched Yb:GAB laser by using a MoS 2 /graphene heterojunction, realizing a minimum pulse width of 370 ns and a single pulse energy of 0.743 µJ . Very recently, our group demonstrated and compared the output performances of passively Q‐switched lasers based on G/MoS 2 heterostructures consisting of monolayer graphene and different MoS 2 layers, and we obtained a femtosecond CW mode‐locked solid‐state laser operating at 1.0 µm with a G/MoS 2 heterostructure as its SA.…”

All solid‐state pulsed lasers (ASSPLs) play a significant role in the fields of medical, military, industry, and scientific research. Passive Q‐switching and mode‐locking are two of the most effective techniques for generating ASSPLs, in which a saturable absorber (SA) is the key element that has great impact on laser output parameters. Recently, 2D layered materials have been widely studied due to their intriguing properties. Their advantages of ultrafast dynamic processing, excellent nonlinear optical response, broadband operation, and easy fabrication and integration with lasers, enable them to be excellent SAs. Herein, the recent progress of ASSPLs with 2D layered material‐based SAs is reviewed, including a brief introduction of the fundamental characteristics, fabrication methods, characterization techniques of ultrafast dynamics, and nonlinear optical properties of 2D materials, design criteria of passively Q‐switched and mode‐locked bulk lasers, and their applications in ASSPLs. Finally, the potential developments and perspectives on 2D material‐based ASSPLs are also highlighted.

“…In this letter, based on Yb 3+ :GdAl 3 (BO 3 ) 4 (Yb:GAB) crystal that has been demonstrated as a splendid laser gain medium [20,21], we reported the frequency stabilization of BP and realized a dual-wavelength passively Q-switched solid-state pulse laser operation using BP as a saturable absorber (SA). The spectrum of a continuous-wave laser, a frequency-selecting laser with quartz etalon and a frequency-selecting laser with a BP SA on a quartz substrate were explored, respectively.…”

We have achieved a dual-frequency passively Q-switched Yb 3+ :GdAl 3 (BO 3 ) 4 solid-state laser at 1042.6 and 1045.0 nm, in which suppressing wavelength time-jittering and building Q-switched pulses both took advantage of the nonlinear loss of black phosphorus prepared by liquid phase exfoliation. It shows the good frequency stabilization effect of a black phosphorus (BP) saturable absorber. A 355 ns pulse laser with pulse energy of 0.889 µJ was achieved. This work validates the capability of BP to convert nonstable multi-wavelength emission into certain stable multi-wavelength emission owing to its nonlinear absorption. Many other multiwavelength lasers will rely on such a modulation performance.
