Device to measure pulse duration at 400nm

The autocorrelator to measure the duration of frequency doubled pulses of a Ti:Sa laser developed in MBI uses a new principle, namely self-diffraction in a material with a high polarisation vector /3 like sapphire. The fundamental beam (800nm) is split into two parts and then focused in non-linear medium a thin sapphire plate.

Temporally and spatially overlapped, the beams interfere producing such an intensity dependent phase diffraction grating, which scatters the beams. The intensity of the diffracted signal is recorded depending on the delay between the 2 beams.
