Abstract:

A Continuous Wave Laser Damage computer program CLAD has been developed to compute material damage caused by a high power laser beam impinging on material surfaces. The program includes three-dimensional conduction, temperature dependent thermal properties, radiation relief, aerodynamic heating, laser radiation heating, heats of fusion and vaporization, chemical ablation, and material removal for flat and cylindrical bodies. The program uses finite difference techniques to compute mass loss and temperature histories of laser irradiated metals, ceramics, and ablatives. This report describes the computational methods contained in CLAD, along with some of the assumptions and limitations contained therein. The report is written as a users manual and contains a description of the main program required to perform a CLAD analysis. Also included is a sample problem, the corresponding main program, and printed output, which will familiarize the user with an actual application of CLAD.
