In this paper, we have developed a high-performance injection-seeded optical parametric oscillator (OPO) based on periodically poled KTiOPO<sub>4</sub> (PPKTP). Because this NLO approach does not entail population inversion and avoids associated refractive index variations, it generates narrowband tunable light pulses at ~840 nm with <5 muJ energy. These have well-characterized shot-to-shot...
We simulate spectro-temporal processes in a nanosecond injection-seeded optical parametric oscillator. Our simulations accurately predict the experimental behavior for the frequency chirp, optical bandwidth, and spectral purity, including effects that are not readily observed directly.
