Lasers for Defense and Security

09/10/2014

Used widely now, lasers will become ever more common tools for both military and security personnel. Laser weapons for missile defense, laser designation, infrared countermeasures (IRCMs), laser ranging, laser “dazzlers,” and other applications are in common use now, while other equipment is in development. In this webcast, contributing editor Jeff Hecht describes the leading uses of lasers for defense and security.

Simulating Laser Material Processing using COMSOL Multiphysics

08/07/2014

The transformation of materials using focused laser beams fundamentally involves multiple physical phenomena such as optical absorption, heat transfer, structural mechanics, and material phase transitions. In this webinar we will describe two examples of laser material processing, resonant IR laser ablation and laser-based chemical vapor deposition. We use COMSOL Multiphysics to solve the coupled phenomena that drive material transformation. In each case, a direct comparison with experimental results is used to validate the model and optimize process parameters. The webinar includes a demonstration and concludes with a Q&A session.
