“…In order to investigate the characteristics of the Q-switched operation more deeply, we measure the optical spectrum and the radio-frequency (RF) spectrum at a fixed pump power of 70 mW. As shown in figure 6(a), the optical spectrum of Q-switched pulses is centered at 1567 nm, which is similar to what was observed in [33]. Although the Q-switched fiber laser in [33] works in the net anomalous dispersion regime and our Q-switched fiber laser works in the net normal dispersion regime, their spectra are the same.…”

This paper presents a stable all-fiber Q-switched Er-doped fiber (EDF) laser with WS2/fluorine mica (FM) as the saturable absorber (SA). The SA device is obtained by depositing WS2 nanosheet layers onto a 20 µm thick one-layer FM substrate using a thermal decomposition method. The modulation depth (MD) of the SA is 8.22% and the non-saturable loss (NL) is 16.38%. By inserting the SA into the EDF laser cavity, stable Q-switched operation is achieved with a central wavelength of 1567 nm. The repetition rate can be tuned from 20.98 kHz to 33.74 kHz and the pulse duration can be adjusted from 8.3 µs to 6.98 µs by increasing the pump power. The maximum output power and the maximum pulse energy are measured to be 2.07 mW and 61.4 nJ, respectively. The experimental results evidently show that the WS2/FM can be regarded as a high-performance SA for fiber lasers.

“…Generally, the commonly used passive Q-switching technology has been of great interest because it has a compact structure and no need for additional modulation and control systems, compared with active Q-switching technology, multi-stage amplification, etc. [7][8][9][10][11][12]. However, the output energy of passive Q-switching still needs to be improved to allow its use in practical applications.…”

Passive Q-switching is an effective approach for generating pulsed lasers, owing to its compact and additional modulation-free design. However, to compare favorably with active Q-switching and multi-stage amplification, the output energy needs to be enhanced for practical applications. Kramers Ytterbium ion (Yb3+)-doped borate crystals, with their excellent energy storage capacity, have been proven to be high-potential laser gain mediums for achieving pulsed lasers with moderate and high output energy using passive Q-switching technology. In this study, the growth, characterization, and laser generation of one Yb3+-doped borate crystal, the Yb3+:ScBO3 crystal, are systematically reviewed. The continuous-wave and passive Q-switching laser characteristics are presented in detail, and the self-pulsations derived from intrinsic ground-state reabsorption are also demonstrated. The specific characteristics and experiments confirm the potential of the Yb3+:ScBO3 crystal for future pulsed laser applications with moderate or even high energy output.
