Abstract:
In this research, a diode‐pumped SnS 2 passively Q‐switched (PQS) V‐type Tm‐doped pulsed laser was demonstrated. The continuous‐wave (CW) condition without SnS 2 saturable absorber (SA) was investigated first. A maximum output power of 1.26W with a slope efficiency of 24.28% was derived at an absorbed pump power of 7.11W under an output coupling of 5%. With the as‐prepared SnS 2 SA employed, a series of stable Q‐switched (QS) pulse trains were successfully realized. A minimum pulse width of 3.061 μs and a maximum repetition frequency of 70.42 kHz were generated through an output coupling of 5%, corresponding to a maximum output power of 621 mW. The delivered highest peak power and maximum single pulse energy were 2.90W and 12.41 μJ under an output coupling of 2.5%, respectively. These findings indicated that SnS 2 was a promising modulator for 2 μm all‐solid‐state pulsed laser generation.
