“…In particular, direct nanosecond pulse generation in a Q-Switched Er:Y 2 O 3 ceramic laser is reported by X. Ren, Y. Wang, J. Zhang, D. Tang, and D. Shen in [6], whereas parametric down-conversion is exploited in a cw-OPO based on a periodically-poled Lithium Niobate crystal to generate a multi-Watt output tunable between 2.4-2.9 µm or 3.14-3.45 µm, depending on the nonlinear crystal poling period (Y. Liu, X. Xie, J. Ning, X. Lv, G. Zhao, Z. Xie, and S. Zhuin in [7]). …”

“…In 2017, a mechanically Q-switched 2.7 μm Er:Y 2 O 3 ceramic laser was demonstrated. 25) This laser attained approximately 3 kW peak power and 80.8 μJ pulse energy. High peak power and high pulse energy can be expected by using a mechanical Q-switch owing to a larger modulation depth and slower frequency.…”

We developed a compact and low-cost diode-pumped ∼3 μm mechanically Q-switched Er:YAP laser with high-power using an optical chopper. At 2.4 W pumping and 7 kHz modulation frequency, a stable single-pulse repetitively Q-switched laser with a wavelength of 2.796 μm has been observed. We recorded the pulse duration, the peak power, and the pulse energy of 264 ns, 22 W, and 5.9 μJ, respectively. As increasing pumping power to 7.4 W at a frequency of 10 kHz, the lasing wavelength shifted to 2.921 μm and a stable multiple-pulse laser was observed. The pulse with 75 ns duration and 34 μJ energy has been observed, corresponding to a peak power of 456 W. The peak power and the pulse energy are the highest value ever reported for an actively Q-switched mid-infrared (IR) Er:YAP laser. Thus, this laser has the potential to be utilized for industrial and science fields as high-power mid-IR light source.

“…K. S. Bagdasarov et al produced the first 2.94 μm laser output at room temperature using an Er:YAG crystal in 1983, which paved the way for the study of the 3 μm laser [ 4 ]. According to research, highly doped Er ions are necessary to generate an efficient laser output when YAG-like oxides are used as the laser hosts [ 5 , 6 ]. However, it is challenging to generate crystals with high doping concentrations due to the limitations of the growing techniques.…”

Two-dimensional (2D) materials own unique band structures and excellent optoelectronic properties and have attracted wide attention in photonics. Tin disulfide (SnS2), a member of group IV-VI transition metal dichalcogenides (TMDs), possesses good environmental optimization, oxidation resistance, and thermal stability, making it more competitive in application. By using the intensity-dependent transmission experiment, the saturable absorption properties of the SnS2 nanosheet nearly at 3 μm waveband were characterized by a high modulation depth of 32.26%. Therefore, a few-layer SnS2 was used as a saturable absorber (SA) for a bulk Er:SrF2 laser to research its optical properties. When the average output power was 140 mW, the passively Q-switched laser achieved the shortest pulse width at 480 ns, the optimal single pulse energy at 3.78 µJ, and the highest peak power at 7.88 W. The results of the passively Q-switched laser revealed that few-layer SnS2 had an admirable non-linear optical response at near 3 μm mid-infrared solid-state laser.
