Wave Optics Simulations

07/02/2015

An add-on to COMSOL Multiphysics®, the Wave Optics Module offers capabilities for modeling optical phenomena. The innovative beam envelope method is among the available techniques, and can be used to simulate optical systems with geometries substantially larger than the wavelength. In this webinar, we will discuss applications such as metamaterials, scattering by nanoparticles, directional couplers, and nonlinear optical waveguides. There will also be a demonstration and a Q&A session.

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

06/23/2015

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.

Please join us for this webcast sponsored by Hamamatsu Corporation.

Lens Design – Tools for designing manufacturable aspheres for complex optical assemblies

05/26/2015

Designing aspheres that may be successfully fabricated and tested can be a frustrating experience. The range of possible aspheres is much larger than the range of those that may be fabricated and tested with available tools. There is often little performance penalty involved in keeping aspheres within range, but doing so is difficult.  In this webcast, sponsored by LaCroix Optical, JENOPTIK will describe tools and approaches for designing aspheres that are suitable for MRF polishing and interferometric testing with sub-aperture stitching interferometers.

Femtosecond Lasers – Getting the Photons to the Work Area

05/05/2015

Ultrashort-pulse lasers, both picosecond and femtosecond, are now available from a large number of manufacturers, with new players entering the field at a rapid pace. These lasers, which only a few years ago were only cool toys in the research lab, are now being used extensively in production environments, allowing the microprocessing of materials and in applications that are not possible using longer pulse length lasers. This webinar will focus on Femtosecond lasers in particular and also on clever ways of delivering the photons to the work piece.

Laser Measurements Critical to Successful Additive Manufacturing Processes

04/15/2015

Maximizing the stability of the variables going into any manufacturing process is what ensures ts consistency and high quality. Specifically, when a laser is used during additive manufacturing processes, knowing how the laser interacts with the material is crucial to the success of the parts being built up. But what variables does the laser introduce? How can they be monitored and controlled? How often should measurements be taken? This webinar will discuss all of these questions to help laser users better understand their laser system, and help to ensure a consistent and high-quality laser additive manufacturing process.
