Simulating Laser Material Processing using COMSOL Multiphysics

Date 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.

Mid-infrared lasers in remote chemical sensing – from stand-off detection to atmospheric sounding

07/09/2014

In this webcast, Gerard Wysocki of MIRTHE will discuss the unique remote-sensing capabilities enabled by modern mid-infrared (mid-IR) lasers and novel spectroscopic techniques. Examples will include passive long-range remote sensing instrumentation and active stand-off spectroscopic sensors. Passive remote-sensing instruments show great potential for astronomy and planetary remote sensing applications, while stand-off detection using quantum cascade lasers (QCLs) enables sensitive and baseline-free molecular sensing of, for example, atmospheric nitrous oxide (N2O). Performance in the lab and in the field will be presented.

IR optical systems: managing unique design challenges

05/28/2014

In addition to the typical problems faced by optical designers working in the visible spectral region, designers of optics for IR thermal-imaging systems must contend with the fact that, in the thermal-IR range, housings, baffles, stops, and even the optics themselves emit radiation. This self-emission creates stray-light and vignetting problems that require special design measures and practices. Moreover, the selection of optical materials is somewhat limited. In this webcast, sponsored by Sensors Unlimited - UTC Aerospace Systems, Gary Wiese, a retired Lockheed Martin Fellow, presents an overview of these issues along with a few design examples.
