Abstract
In this Letter, we report, for the first time to our knowledge, on a
continuous-wave, singly resonant optical parametric oscillator using an
MgO: PPLN crystal pumped by an all-fiberized master-oscillator power
amplifier structured amplified random fiber laser. An idler output power
of 2.46 W at 3752 nm is achieved with excellent beam quality, and the
corresponding pump-to-idler conversion efficiency is 9.6% at room
temperature. The idler output power exhibits a peak-to-peak power
stability better than 12.7%, and the corresponding standard deviation is
better than 3.6% RMS in about 20 min at the maximum output power.
Meanwhile, other characteristics of the generated signal and idler laser
are studied in detail and not only offered an effective guide in the
research of optical parametric processes in the case of a continuous
spectrum, but also broadened the range of random fiber laser
applications.
