Abstract

The experimental results of a temporally stable, continuous wave, midinfrared (MIR), singly resonant optical parametric oscillator pumped by an all-fiberized master oscillator power-amplifier structured random fiber laser (RFL) is presented. The maximal idler output power of 4.35 W was achieved at 3271 nm with good beam quality, and the corresponding pump-to-idler slope efficiency was up to 17.1%. The idler output power exhibited a peak-to-peak fluctuation better than 3.2% RMS at the maximum output power over 20 min. Meanwhile, other characteristics of the generated idler MIR laser had been discussed in details, which offered effective guidance on the research of the frequency downconversion process in the case of temporally incoherent light and broadened the range of RFL applications.
