Mechanisms of femtosecond laser-induced refractive index modification of poly(methyl methacrylate) [PDF]

open access: yes, 2010
The mechanisms of refractive index change in poly(methyl methacrylate) by frequency doubled femtosecond laser pulses are investigated. It is demonstrated that positive refractive index modificaton can be caused by a combination of depolymerization and ...
