Abstract

In this paper, a dual-wavelength(DW) mid-infrared optical parametric oscillator(OPO) pumped by a DW fiber laser based on the stimulated Raman scattering(SRS) effect, is demonstrated. When the pump power satisfied the threshold condition, obvious SRS effect was observed and a DW fiber laser with center wavelengths at 1060 nm and 1113 nm was obtained. The DW fiber laser was injected into a single-period crystal, and the whole process went through four stages. In the first three stages, 1060 nm pump laser achieved parametric oscillation and generated 1602 nm signal laser and 3138 nm idler laser and the conversion efficiency was seriously affected by SRS effect. In the fourth stage, two independent parametric processes were realized, which generated two mid-infrared output at 3131nm and 3580nm with powers of 2.46W and 40mW, respectively. The efficiency characteristics in the four stages were also discussed separately.
