Paper Abstract

With the rapid development of micro optoelectronic device and integration techniques in PMMA fiber, micro-structure integration in PMMA fiber such as diffraction gratings graved by focusing fslaser inside the PMMA fiber is becoming popular. However, the white light induced by interaction of femtosecond pulse with PMMA has a property that is similar to laser beam has been founded, and generated a continuous spectrum from ultraviolet to infrared. Ti:sapphire femtosecond laser systems with 1kHz, 45fs, 1mJ were used to get the white continuum spectrum in PMMA . The white continuum spectrum from 440nm to1100nm has been recorded. Also White light filament induced by fslaser at lower thredhold power inside the PMMA than others , and this white light filaments will damage the PMMA fiber and induce refractive-index change so as to affect micro optoelectronic device and integration techniques application in PMMA fiber.
