Analysis of parametric fluorescence amplified in a noncollinear optical parametric amplifier pumped by the second harmonic of a femtosecond Yb:KGW laser
Keyword(s):
We present the results of theoretical and experimental investigation of amplified parametric fluorescence (APF) produced in a high-gain BBO-based femtosecond noncollinear optical parametric amplifier (OPA) pumped at 515 nm. Differences of APF levels in Poynting vector walk-off-compensating and tangential phase-matching amplification geometries are examined. APF suppression due to the presence of a seed pulse in the OPA is measured and is found to be around 6 times in typical OPA operating conditions when pump-to-signal conversion efficiency is 11.5%.
