Birefringence of small apertures for shaping ultrashort pulses
Birefringence of small apertures ultrashort pulses Optics
2012/4/27
For ultrashort pulses having different states of polarization, the experienced time delay when passing through small apertures is different. In the case of a small slit (or a circular aperture), we re...
Modulation Instability of Ultrashort Pulses in Quadratic Nonlinear Media beyond the Slowly Varying Envelope Approximation
Quadratic Nonlinear Media Theoretical model and MI analysis
2011/8/31
We report a modulational instability (MI) analysis of a mathematical model appropriate for ultrashort pulses in cascaded quadratic-cubic nonlinear media beyond the so-called slowly varying envelope ap...
