Heat transfer and thermal stress analysis of a glass beam dump

PDF Version Also Available for Download.

Description

Today`s new generation lasers require durable beam dumps which can absorb large amounts of energy remaining structurally sound. This report analyzes a full scale model of one particular laser glass beam dump which tends to fail in small scale experiments. In these small scale experiments, the laser causes plasma formation on the front face of the beam dump, material spalling off of the back face, and cracking and cloudiness within the glass. This damage is more prevalent when the beam dump has been shot a number of times with the laser. While many phenomena are taking place within this beam ... continued below

Description

Today`s new generation lasers require durable beam dumps which can absorb large amounts of energy remaining structurally sound. This report analyzes a full scale model of one particular laser glass beam dump which tends to fail in small scale experiments. In these small scale experiments, the laser causes plasma formation on the front face of the beam dump, material spalling off of the back face, and cracking and cloudiness within the glass. This damage is more prevalent when the beam dump has been shot a number of times with the laser. While many phenomena are taking place within this beam dump, this report focuses solely on thermal effects - whether the thermal effects of laser deposition on the full-scale glass beam dump will cause failure within the glass.
