Theoretical Study of Drilling Process Materials By Laser Pulses (Micro, Nano and Picoseconds)

Ikhlas Jabir Mahmood

Abstract: study of the interaction of laser radiations (Nd-YAG) laser at (1.0 6m) wave length with pulse duration (100 sec) on some solid material (Ag, Au, Sn, CO) by using three dimension function solutions that is laser beam transition function and through this we can study thermal distribution on surface and into materials and thermal dropping into material when the laser beam intensity is steady and variable with time. from research results seem that the thermal distribution into material and on surface is decrease when the laser beam intensity is variable with time. we conclude that the absorption coefficient of material is grater when the interaction process is better. In research we are using matlab 7 program for applications.

Keywords: interaction of laser, pulse duration, laser radiations, solid material, thermal distribution, laser beam intensity
