Ultrafast Four-Wave Optical Parametric Amplification in Transparent Condensed Bulk Media
Figure 4
Normalized autocorrelation functions of (a)
input pump pulse, (b) depleted pump pulse at the FWOPA output, (c) input seed
signal, and (d) output amplified signal. Red curves represent a corresponding
Gaussian fit. Output pulses were measured after propagation in 40-mm-long water
cuvette, with J and pump-to-signal conversion of 15%.
