Research on the Thermal Effect of Long Pulse Laser Irradiation BK7 Glass

摘要：

　　The temperature and thermal stress distribution on BK7 glass was numerical simulated by MATLAB according to heat conduction theory.Research has shown that the laser pulse number,spot radius and pulse width can change the extent of the damage threshold for BK7 glass.The results shown the damage threshold decreased with the laser pulse number and radius increasing.The laser power also increased with the pulse width reducing.At the same time,the damage threshold was corresponding reduced.
