Abstract
We present a Yb:fiber-pumped MgO:PPLN optical parametric oscillator which employs a ring cavity incorporating Pellin-Broca prism retroreflectors. Pumped by chirped pulses centered at 1033 nm, the signal wavelength is tunable over 380 nm (1541 nm to 1921 nm), with a maximum output power of 647 mW and a pump-signal conversion efficiency of 33.3 . The signal temporal profiles were measured via second-harmonic FROG revealing a FWHM of 317 fs. With a cumulative RIN standard deviation of ∼0.18 , this system further highlights the benefits of intracavity folding prisms in the construction of highly stable ultrafast OPOs.
