SUMMER INTERNSHIP REPORT FINITE ELEMENT TRANSIENT THERMAL ANALYSIS OF LASER WELDING PROCESS ABSTRACT In this project‚ Laser welding process has successfully been used for joining of two stainless steel plates. The sizes of the metal plates are 50mmX40mmX2mm each. The distribution of the temperature field in laser welding using stainless steel sheets were simulated by ANSYS. The thermal properties which have been used for thermal simulation are assumed to be varying with temperature

an Erbium Doped Fibre Amplifier (EDFA) by using a tuneable Long-Period Grating ) (LPG). The gain spectrum of an EDFA at a wavelength of ) 1530nm was equalized from 5.2dB peak-to-peak to 2.3dB peak-to-peak. The LPG was fabricated by using an excimer laser and a metal mask. By means of a novel technique that enables one to tune the peak attenuation of the LPG‚ the gain equalizer can operate over a wide range of pump power.
