ABSTRACT
Heat accumulation by high repetition rate femtosecond laser irradiation inside glass generates a much larger modification than that by a single pulse. In this study, we determined the temperature distribution due to heat accumulation and the characteristic temperature for heat modification inside a soda lime glass by analyzing the relationship between the radius of modification and glass temperature. The validity of the analysis was confirmed by reproducing the modification due to two-beam irradiation. The determined characteristic temperature suggested that the temperature distribution and the spatial dependence of the stress relaxation are important in the mechanism of heat modification.

    It has been demonstrated that femtosecond laser pulses can be used to process dielectric materials such as optical glass. One of the applications of this process is to produce sub-diffraction-limit structures whose index of refraction is different from that of the host medium. Due to the small...
