Abstract

We report a greater than 20-fold compression during second-harmonic generation from an active–passive mode-locked Nd:YAG laser controlled by passive negative feedback. A compression ratio of 32 times is achieved in the beam center, resulting in a pulse duration of 360 fs.

Energy and duration of the SH pulse: (a) The autocorrelation width for the full beam (squares) and the beam center (stars) as well as the pulse energy (circles) are plotted as a function of delay between e- and o-polarized fundamental pulses; the fundamental pulse intensity is Ie + Io = 2.3Ie = 3.5 GW/cm2. (b) The spatial distribution of fundamental (diamonds) and SH (circles) pulse energies, for Ie + Io = 2.3Ie = 3.2 GW/cm2 and a predelay of the e wave of 12 ps. The autocorrelation width of the SH is also plotted as a function of the radial coordinate (squares).

Plots of the autocorrelation of compressed pulses (averaged over the beam profile) for three different values of the ratio of fundamental pulse energies. The predelay of the e wave is 11 ps, and the pump intensity is Io = 2.5 GW/cm2. The numbers in parentheses indicate the pulse durations for sech2 shapes.

Autocorrelation of a compressed SH pulse measured on the beam center at a pump intensity of Ie + Io = 4.2 GW/cm2. The predelay between e and o waves is 11 ps. The intensity ratio Io/Ie is 1.3.
