Abstract
We report a high-power, cw, singly resonant optical parametric oscillator (SRO) using a simple, compact fiber pump laser architecture in the green. The SRO, based on MgO:sPPLT, is pumped by of single-frequency cw radiation at obtained by single-pass second-harmonic generation (SHG) of a Yb fiber laser, also in MgO:sPPLT. Using two identical crystals of length for SHG and SRO, we generate cw idler powers of up to over , with a peak-to-peak power stability over , in a spatial mode with . Using finite output coupling of the resonant wave, we extract of signal power with peak-to-peak power stability over , and a frequency stability over . The signal and idler output have beam profile with across the tuning range.
