A single crystal of ytterbium-doped “mixed” yttrium–lutetium aluminum garnet with a stoichiometric composition of (Y0.601Lu0.233Yb0.166)3Al5O12 was grown by the Czochralski method and its structure, vibronic, spectroscopic, and laser properties were studied. The stimulated-emission cross-section for Yb3+ ions was maximized to 2.53 × 10−20 cm2 at 1031 nm. The emission bandwidth was ~8 nm, and the reabsorption-free luminescence lifetime of the 2F5/2 state was 1.063 ms. Pumped at 941 nm, the Yb laser generated a maximum output power of 1.04 W at 1.03 and 1.05 μm with a high slope efficiency of 76.4% and a laser threshold of 76 mW. A continuous wavelength tuning over a range of 51.6 nm (1026.4–1078.0 nm) was also achieved. Power scaling was achieved using a 969 nm diode-pumped microchip cavity. A maximum output power of ~9 W was obtained at 1.05 μm with a slope efficiency of 76% and an almost circular laser beam profile.

“…In particular, the strong nonlinear absorption mechanism based on the Pauli incompatibility principle makes 2D material-based SAs indispensable modulators in ultrafast fiber lasers. With the significant success achieved by graphene-based SA in ultrafast fiber lasers for the first time, various new types of 2D materials, including topological insulators (TIs) [20][21][22][23][24], transition metal dichalcogenides [25][26][27][28][29][30][31][32], MXenes [33][34][35][36][37][38], and Xenes [35][36][37][38], have been proposed and applied. These materials have demonstrated different soliton phenomena and ultrafast pulse generation in fiber lasers.…”

Some two-dimensional (2D) layered mono-elemental materials have been reported as saturable absorbers (SAs) for the generation of various soliton phenomena, and many excellent results have been achieved. In our experiment, we made thin films of Germanene-polyvinyl alcohol (Ge-PVA) and applied them as saturable absorber (SA) in Er-doped fiber lasers (EDFL), investigated Ge's characteristics, and demonstrated the conversion from mode-locked to Q-switched mode-locked (QML). The conventional mode-locked operation with a repetition rate of 9.63 MHz and a central wavelength of 1559.7 nm was stably triggered when the pump power exceeded the threshold of 40 mW. QML pulse with a central wavelength of 1530.26 nm and the maximum pulse energy of 86 nJ can be obtained by changing the pump power and polarisation state of the light in the cavity. This work reveals the excellent optical properties of Ge SA in ultrafast fiber lasers and provide a new approach for the generation of QML pulses.

“…Nd: GSAG laser using saturable absorber molybdenum disulfide (MoS 2 ) is a passive type that can be implemented in low-cost integrated applications, has been reported for the first time to achieve dual-wavelength, and has received much attention. As with Q-switching, access dual wavelengths using the mode-locked method in a recently proposed erbium-doped fiber laser demonstrates the capability of the mode-locked method [11], [12]. ML method is the most crucial technique for generating consecutive pulses [13].…”
