Compact and versatile OPG-OPA based on a periodically poled nonlinear crystal pumped by femtosecond Ytterbium fiber laser
Résumé
A 10 mm long PPLN crystal pumped by 125 nJ, 250 fs pulses centered at 1035 nm yielded by Yb3+ femtosecond fiber oscillator generates femtosecond signal and idler pulses tunable in the 1.35 µm-1.65 µm and 2.6 µm-4.2 µm spectral ranges. A numerical model accounting for both second-and third-order nonlinear processes well agree with the recorded signal conversion efficiency (up to 42%), the spectral and temporal profile of the generated pulses. Pulse to pulse stability is drastically improved injecting this compact and versatile device with a continuum generated in a photonic fiber. Further improvements are discussed.
