Abstract

In this paper, the electromagnetic field, temperature field and stress field distribution of gold coated gratings were calculated to analyze the damage mechanism under ps-pulsed laser irradiation. The finite element method in time domain was used in calculation. The Maxwell's equations were used to calculate the electromagnetic field, the Fourier's law of heat conduction was used to calculate the temperature field and the Hooke's law was used to calculate the stress field. The influences of photoresist parameters on temperature and stress fields in gratings were analyzed. The results reflect that using photoresist which has a high thermal conductivity, low thermal expansion coefficient and low elasticity modulus to fabricate bottom gratings is considered useful for improving damage threshold of gold coated gratings.
