Abstract

We observe new effects in frequency doubling of colliding-pulse, mode-locked dye-amplified pulses (300 fsec, 620 nm, up to 1 mJ of energy) due to phase mismatch. If the second-harmonic generation in the nonlinear crystal (30-mm KDP crystal) is phase matched, the output is a square pulse. In contrast, when a phase mismatch is introduced, the generated pulse contains two peaks. We observe that the time profile is affected by depletion and chirp of the fundamental. The experimental results agree well with our numerical calculations.

Experimental setup. The fundamental CPM pulse is divided by a beam splitter, and one of the pulses is doubled in a 30-mm KDP crystal. The fundamental is stopped by a filter (F). The generated UV light is downconverted, with the residual CPM pulse, in the second KDP crystal. The downconverted signal is measured by using a photodiode (PD). The cross-correlation signal between the generated UV light and the CPM pulses is measured as a function of the delay.

Measured (solid curves) and calculated (dashed curves) second-harmonic profile of a 300-fsec pulse doubled in a 30-mm KDP crystal without phase mismatch. The results are plotted for (top) a low intensity (I = 3.0 × 106 W/cm2) and (bottom) a high intensity (I = 1.7 × 109 W/cm2).

Measured (solid curves) and calculated (dashed curves) second-harmonic profile of a 300-fsec pulse doubled in a 30-mm KDP crystal with different phase-mismatch conditions. The results are plotted for (top) a small phase mismatch (Δk = 28 cm−1) and (bottom) a large mismatch (Δk = 62 cm−1).
