The pulse laser using a saturable absorber as a passive device has the advantages of narrow pulse width, high repetition rate, and high pulse energy. Low‐dimensional materials have attracted research interest in recent years due to their excellent saturable absorption properties, ultra‐fast carrier response speed, high damage threshold, and so on. This paper gives a brief review of the state‐of‐the‐at 2 µm solid‐state lasers using saturable absorbers. The output performance of lasers in repetition rate, pulse energy, pulse width, and wavelength are summarized. The paper is expected to provide a development direction of novel materials as saturable absorbers in 2 µm solid‐state lasers.

“…At the same time, some miniaturized lasers are imperceptibly changing the production mode of traditional industries and improving the quality of human life. Based on mode-locking technology, we can obtain ultrashort pulse output in fiber lasers. − At first, active mode-locking technology is used to realize the mode-locked state, but this method would introduce acoustic-optical or electro-optical modulators into the resonator, which would bring large insertion losses and seriously affect the output power and energy efficiency of the laser. After the passive mode-locking technology was discovered, the acquisition method of an ultrafast laser is further expanded, and the ways of phase locking and pulse narrowing such as nonlinear polarization rotation or saturable absorber (SA) were invented.…”

As a handicap for passive mode-locked lasers to operate stably for a long time, the undesirable damage threshold of saturable absorption devices means that it is difficult to maintain a normal operation state under the irradiation brought by ultrashort pulses. To reduce the damage probability when the saturable absorption devices interact with an ultrafast laser, some technologies have been developed to resist the high-energy irradiation of an ultrafast laser that will also increase the difficulty of laser construction at the same time. In this paper we put forward a new research idea to improve the low-damage threshold problem: optimizing the optical transmittance, which will avoid dissociation due to excessive heat accumulation. Using the melt and machine exfoliation method, the high optical transmittance (>95%) saturable absorption devices based on Bi 2 Se 3 are prepared, whose damage threshold (2.45 mJ/cm 2 ) is nearly 5 times higher than commercial SESAM. The devices applied to generate femtosecond pulses exhibit exciting nonlinear optical effects, which enable the mode-locked fiber laser to operate with a pulse duration of 195 fs and a signal-to-noise ratio of 81.73 dB. This discovery not only proves that the passive mode-locked laser-based high transmittance Bi 2 Se 3 can obtain reliable pulse output, but also provides a new perspective for the selection of saturable absorption materials in the future.

“…Ultrafast fiber lasers offer a simple structure, efficient energy conversion rate, tunable output characteristics, and flexible layout, making them highly valuable for various applications, such as photonic chip design [1,2], microcellular imaging [3,4], and precision machining [5,6]. The pursuit of ultrashort pulse outputs in fiber lasers has prompted the exploration of different mode locking techniques [7][8][9][10]. Among these techniques, active mode locking is the first to emerge, relying on external modulation devices.…”

The novel semimetal tantalum phosphide (TaP) is known for its notable physical property including high carrier mobility, zero bandgap structure, and superconductivity. However, there exists no prior record of TaP being harnessed as a saturable absorber (SA) within ultrafast fiber lasers. In this study, ultrasound assisted liquid phase exfoliation is applied to fabricate TaP quantum dots (QDs). Then QDs are subsequently deposited onto the tapered waist of a specialized fiber to create a TaP-SA. The evaluation of nonlinear optical properties is conducted using a two-armed balanced probing device, which yields noteworthy results including a modulation depth of 10.8 % and a saturation intensity of 0.52 KW/cm2. Then, the TaP-SA is applied in Er-doped fiber laser (EDFL) which demonstrates that a steady mode-locked pulse output with an average output power of 3.545 mW and a pulse width of 552 fs is obtained. The intrinsic semimetal properties of TaP underscore its potential in the realm of ultrafast photonic and nonlinear optical devices.
