Recently, companies that perform system integrations have become more concerned about the quality of the laser delivered to the process and not just the quality of the laser source itself. Some companies are now starting to use beam profiling for much more than simply qualifying the laser source. They also leverage the technology to qualify the components that are integrated into their systems and to characterize the application of the laser. Using sample beam profiles as illustrations, this article defines laser quality and provides examples of how laser system quality can be affected by system componentry.
In this article we will discuss how to match an appropriate laser beam profiling technique to a laser application. The discuussion includes building an aligned optical system, collimation and focusing, high power laser quality measurements, and proper attenuation techniques.
The New Year is a time to look back on the past year and contemplate on how to do things better. It’s a time to make New Year’s resolutions in an effort to be a better person. One of the most common and popular New Year’s resolutions is the renewed commitment to losing weight. As many of us are all too familiar with, that means eating better and getting involved in a regular exercise routine. One of the advantages of losing weight in the 21st Century is the technology at our fingertips that helps us reach those goals. From the sciences behind how the body uses the food we eat, to the plethora of Smartphone apps that help us measure and track our results, it seems like losing weight would be an easy task. So why is it not? By John McCauley, Midwest Sales Manager, Ophir-Spiricon
It all started when a slow-witted engineer was teased one too many times. Tired of being the butt of all his colleagues’ jokes, he plotted revenge. By Ephraim Shafner, Ophir Photonics
A research organization was developing a critical procedure that required a pulsed DUV laser beam at 193nm. By Dick Rieley, Mid-Altantic Regional Sales Manager, Ophir Photonics Group
Measuring the propagation parameters of a laser beam is an important method of understanding the quality of the laser beam and predicting its performance for various laser applications. By Allen Cary, Director of Marketing, Ophir-Spiricon
