Using second-harmonic frequency-resolved optical gating and a tricyanovinylaniline polymer thin film, we have measured the amplitude and the phase of mode-locked Ti:sapphire laser pulses as short as 13 fs. These thin films are ideally suited for ultrashort-pulse diagnostics because they eliminate the angle tuning associated with birefringent phase-matched(More)
We discuss the molecular engineering of a second order nonlinear optical (NLO) polymer materials specifically for ultrashort optical pulse diagnostics. We use second harmonic generation (SHG) frequency resolved optical gating (FROG) to measure the amplitude and phase of an ultrashort pulse. It is shown that thin poled TCV/PMMA are sufficiently nonlinear and(More)
