Figure 4

Simulated 3.2 μm idler waves of the narrow-band seeding OPA.

The left column of (a) to (e) shows the temporal intensity of mid-IR pulses while the pump duration is 50 fs. From top to bottom, the type-0 (a) and type-I (c) QPM situations were considered and the dispersion compensated pulses of type-I was presented in the bottom (e). The right hand column of (b) to (f) shows the cases of 100 fs pump duration. Inset: The corresponding spectral intensity and phase. The pulse intensity was respectively normalized to the compressed cases of (e) and (f) with the same pump duration.
