Proceedings PaperReflection and transmission of femtosecond pulses
|Format||Member Price||Non-Member Price|
Instead of using a frequency dependent refractive index, we propose an alternative method to describe reflection and transmission of femtosecond pulses at the boundary of a new medium. It is a time dependent perturbation treatment of the problem, that follows explicitly the evolution of an ultrashort pulse passing through the boundary. The reflection and transmission properties depend on the relation between the pulse length and the relaxation time of the material.
