Analysis on the thermal effect of the silicon material induced by laser pulse trains

Laser pulse train will cause the temperature accumulation in infrared material. To analyze the thermal damage characteristics of silicon material that induced by different laser pulse trains a practical model has been established. By using the heat conduction equation, the thermal incubation effect in silicon material has been calculated. Furthermore, the temperature accumulation processes caused by different pulse trains are simulated. The results show the temperature variation behavior and the thermal damage characteristics of silicon material clearly.
