G. Cipparrone et al., A NEW APPLICATION OF POLYMER-DISPERSED LIQUID-CRYSTALS - MEASUREMENTSOF ULTRASHORT LIGHT-PULSES WITH FEMTOSECOND ACCURACY, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 263, 1995, pp. 521-528
The self-diffraction technique has been applied to measure subpicoseco
nd pulsewidth using Polymer Dispersed Liquid Crystals as nonlinear mat
erials. The experimental data agree with the ones obtained by conventi
onal autocorrelation technique thus pointing out the advantages of che
ap and handy PDLC over commonly used high optical quality nonlinear cr
ystals.
