Abstract

Highlights: A 1.57 μm and 3.84 μm multiple OPO is realized using only single MgO:APLN crystal. The multiple OPO pumped by a high repetition rate, high-power 1.064 μm MOPA laser. Powers of 6.5 W at 1.57 μm and 4.3 W at 3.84 μm were obtained simultaneously. This work opens a new door for the high performance 1.57 μm and 3.84 μm laser. Abstract: This paper presents a high repetition rate and high power 1.57 μm and 3.84 μm multiple optical parametric oscillator based on a single MgO:APLN crystal and pumped by a pulsed 1.064 μm MOPA laser for the first time. In the experiment, with a repetition rate of 200 kHz, a maximum average output powers of 6.5 W at 1.57 μm and 4.3 W at 3.84 μm were obtained under 49 W of 1064 nm pump power, corresponding to optical–optical conversion efficiencies of 13.3% and 8.8%, respectively. The pulse widths were 12.8 and 11.2 ns for 1.57 μm and 3.84 μm, respectively, at the maximum output power.
