A stable, passively Q-switched Yb:CaGdAlO laser based on Mo:BiVO saturable absorber was demonstrated. Close observations of the structure and morphology of the nanoparticles by using transmission electron microscope, Raman spectrum and linear absorption were measured. The nonlinear transmission of Mo:BiVO was characterized by a 30 ps laser with a central wavelength of 1064 nm and a repetition rate of 10 Hz. The experimental maximum output power of the pulsed laser was 510 mW with a repetition rate of 87 kHz and pulse width of 3.18 μs, corresponding to a peak power of 1.84 W and a single pulse energy of 5.8 μJ. The experimental results indicate that Mo:BiVO-SA is a great candidate for passively Q-switched lasers in the near infrared region.

Janus transition metal disulfide (TMD) monolayers have two distinct carbon surfaces that break the inherent ground external mirror symmetry. When compared to traditional TMD materials, Janus TMDs not only inherit the advantages of traditional TMDs but also have new characteristics that are different from those of traditional TMDs.
