Passive Q-Switching of a Diode-Pumped Pr:LiYF<sub>4</sub> Visible Laser Using WS<sub>2</sub> as Saturable Absorber

Q-switched laser operation of a blue-diode-pumped Pr:LiYF<sub>4</sub> laser is demonstrated at 640 nm for the first time by using a tungsten disulfide (WS<sub>2</sub>) nanosheet material as a saturable absorber. Stable laser pulses of 630 ns are obtained with a pulse repetiti...

Description
Summary:Q-switched laser operation of a blue-diode-pumped Pr:LiYF<sub>4</sub> laser is demonstrated at 640 nm for the first time by using a tungsten disulfide (WS<sub>2</sub>) nanosheet material as a saturable absorber. Stable laser pulses of 630 ns are obtained with a pulse repetition rate of 88 kHz, a pulse energy of about 0.24 <inline-formula> <tex-math notation="LaTeX">$\mu\text{J}$</tex-math></inline-formula>, and an average output power of 21.5 mW. This paper broadens the application of WS<sub>2</sub>-like 2-D nanosheet saturable absorbers from the near- and mid-infrared to the visible domain.
