Femtosecond Lasers – Getting the Photons to the Work Area

Date 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.

Ray Optics Simulations with COMSOL Multiphysics

04/02/2015

The Ray Optics Module can be used to simulate electromagnetic wave propagation when the wavelength is much smaller than the smallest geometric entity in the model. Notable features include built-in settings for analyzing intensity and polarization, dedicated capabilities for unidirectional or bidirectional coupling to other physics interfaces for industrial-grade multiphysics applications, and a wide variety of boundary conditions, including refraction and combinations of diffuse and specular reflection. The webinar, sponsored by Comsol, will include a demonstration and will conclude with a Q&A session.

Handheld Spectrometers

02/24/2015

Spectroscopy is a powerful and versatile tool that traditionally often required a large and bulky instrument. The combination of compact optics and modern packaging with powerful spectral sensors and microprocessors has allowed development of handheld spectrometers. This talk will review the basic principles, describe the range of instruments, and explain how some of them work.

Fracking, climate change, and lasers:  new tools to reduce fugitive methane emissions

01/28/2015

This webcast, sponsored by Hamamatsu Corporation, covers recent developments and field deployments of compact quantum-cascade-laser (QCL)-based methane sensors to quantify methane emissions from the Barnett, Marcellus, and Monterey Shales. Fugitive methane concentrations, plume sizes, and distribution of emissions rates from shale gas extraction, storage, and transmission will be presented, along with a summary of the technical and sampling challenges needed to quantify fugitive methane emissions from the lifecycle of the natural-gas supply chain.
