“…Compared with active methods, passive methods are simple, compact, cost-effective, and satisfactory. According to reports, various materials including semiconductor saturated absorption mirrors (SESAM) [5], carbon nanotubes [1], graphene [6], transition metal dichalcogenide [7], and black phosphorous [8] were promising SAs. SESAM is characterized by a low damage threshold, narrow bandwidth, and high manufacturing cost, whereas other materials pose challenges in terms of fabrication and long-term stability.…”

This work demonstrates a single mode fibre-step index multimode fibre-single mode fibre (SMS) structure as saturable absorber (SA) to generate Q-switched laser based on the Kerr-effect of multimode interference (MMI) in an Erbium-doped fibre laser (EDFL) cavity. A 156 mm length of step index multimode fibre (SIMF) was spliced directly into a ring cavity to modulate the cavity loss. By bending and applying proper pressure on the SIMF, steady Q-switched pulse was generated without strict length restriction of the SIMF. The Q-switched laser had a high repetition rate from 87 to 158 kHz, while the corresponding pulse width was low, ranging from 4.2 μs to 2.5 μs as the pump power increased from 115 to 342 mW. The signal-to-noise ratio (SNR) of the fundamental mode for the pulsed laser was about 67 dB at a central wavelength of 1530 nm. The experiment demonstrated that SMS structure can be used as stable SA to generate Q-switched laser for high power applications. It also indicated that even with large core diameter step index multimode fiber, SMS structure can be utilized to generate stable Q-switched pulsed laser with very simple cavity settings.

“…The quest for ultrashort pulses has led to the widespread adoption of passive mode-locking techniques, primarily relying on saturable absorbers (SAs). Notably, a range of SAs has been investigated, encompassing semiconductor saturable absorber mirrors (SESAMs), carbon nanotubes, and two-dimensional (2D) nanomaterials like graphene [3][4][5]. Most of the commercial laser products used SESAM as SA.…”

We have successfully generated soliton mode-locked pulses in a ring Erbium-doped fiber laser (EDFL) cavity using molybdenum disulfide (MoS2) saturable absorber. The MoS2 thin film was grown onto ITO substrate through electro-deposition process using a mixture of 0.5M H2MoO4 and 0.5M Na2S2O3.5H2O as electrolyte solution. The EDFL produced stable soliton pulses operating at centre wavelength of 1557 nm and repetition rate of 1.88 MHz. The mode-locking was realized by injecting pump power within a range from 77 mW to 124 mW. It generates the maximum output power of 0.7 mW and pulse width of 3.0 ps.

Exploring advanced saturable absorber (SA) materials that exhibit exceptional performance for achieving Q-switching and mode-locking operations remains a vibrant area of research in the field of fiber lasers. The remarkable optical nonlinearity, coupled with high thermal and chemical stability of MAX phase materials, positions them as promising candidates for high-performance SAs. In this study, we demonstrated the potential of Ti 3 AlC 2 MAX phase as an effective material for Q-switched and mode-locked fiber laser applications. The Ti 3 AlC 2 film was synthesized through a straightforward and cost-effective casting method employing polyvinyl alcohol (PVA) as a host material. The SA was cleverly constructed from the film, utilizing a sandwichstructured fiber-ferrule platform, and seamlessly integrated into an Erbium-doped fiber laser (EDFL) ring cavity. Initially, a stable Q-switched laser was realized at a center wavelength of 1531 nm. The repetition rate exhibited a commendable increase from 35.0 to 50.8 kHz, and the pulse width reduced from 6.58 to 3.40 µs as the pump power was adjusted within the range of 25.98 to 58.29 mW. Notably, the maximum output power of 2.49 mW and a pulse energy of 49.02 nJ were recorded at a pump power of 58.29 mW. Subsequently, an additional 200 m long single-mode fiber was added into a similar laser cavity, leading to the generation of a stable modelocked laser at a threshold pump power of 81.37 mW, operating at a central wavelength of 1558.96 nm. The observed stable repetition rate of 969.3 kHz, coupled with a pulse duration of 300 ns, demonstrated robust performance as the pump power increased from 81.37 to 113.68 mW. These findings highlight the exceptional performance of Ti 3 AlC 2 SA for both Q-switching and mode-locking applications. The versatility of these lasers makes them valuable for diverse applications, including micromachining of materials, frequency comb generation, and remote sensing.
