Variable White–Light Filaments Induced by Femtosecond Laser in PM567-Doped PMMA

Abstract:

Interactions of femtosecond–laser with various transparent media are great focused recently because of some interesting phenomena produced. This experiment is aimed to investigate super-comtinuum generation of femtosecond lasers (800nm, 1 kHz) with PM567-doped PMMA polymers. And we, to our knowledge, first founded: variable white light filaments in which spectrum changed from super continuum to pumped light spectrum. The circle structures of the variable spectrum are recorded and are analyzed in theory and experiment; moreover, the effect of interaction time on the filaments; last, founding PM567-doped PMMA has the properties of the Photorefractive crystal in the field of super-comtinuum generation.
