Frontiers of Information Technology & Electronic Engineering 2021, Volume 22, Issue 3,   Pages 312-317 doi: 10.1631/FITEE.2000110

Abstract: Developing new saturable absorbers for use in the mid-infrared region has practical significance for short-pulsed lasers and related scientific and industrial applications. The performance of (GNRs) as saturable absorbers at novel mid-infrared wavelengths needs to be evaluated even though these benefit from ultrafast nonlinear responses and broadband saturable absorption. of an LD-pumped Tm:YLF laser using GNRs was successfully realized in this study. Pulses with an 843 ns pulse width and a 6.67 kHz repetition rate were achieved using this Q-switched laser. Results showed that GNRs provide promising passive Q-switches for Tm-doped lasers.
