laser beam profiling White Papers
ISO Compliance of Non-Contact, Real-Time Beam Analysis
Laser power levels used in production have risen significantly. Welding systems commonly use laser powers in the range of multiple kW. To deliver high product quality, key parameters of the laser beam must be measured regularly. Ophir has tackled the task and developed a non-contact measurement technology based on Rayleigh scattering that enables the measurement of high-power beams without touching the laser. Here we show how this technology fully complies with the ISO11146 standard.
Industrial Laser Measurement Systems: Best Practices
When discussing laser applications, regardless of how the laser is used, it is imperative to understand how the laser is interacting with the material being processed. This article will detail why a laser’s performance is important for industrial...
VCSEL Measurement Solutions
Vertical Cavity Surface Emitting Lasers (VCSELs) are a type of semiconductor laser diode. Unlike edge emitting laser diodes, VCSELs emit upwards and thus can be easily packaged as emitter arrays containing hundreds of emitters on a single chip. Many...
Measuring Small-Beam MFD: Overcoming the Challenges
Small beams are used in many critical applications, such as such as fiber optic coupling efficiency, defect scanning, optical design, and optical fabrication process control. Yet often, they are not directly profiled because determining the size of...
Modifying Laser Beams: There’s No Way Around It, So Here’s How
In order to apply a laser to an industrial process, medical therapy, or communications technology, it is usually necessary to modify the laser beam to achieve the desired results. Laser beam measurement tools make this possible. Here's how to match...
Beam Profiling: A Brief Review of Best Practices
Currently, lasers that vary widely in light wavelengths and beam powers are available for many scientific, industrial, and medical applications. This article reviews the components that comprise a laser beam profiler, and describes the methods of...
Reducing Production Waste with Laser Profiling and Characterization
A laser profiling system can characterize and identify which variables affect product quality and waste. But many laser users have never evaluated the quality of the beam beyond the initial delivery. This leads to frequent process adjustments to try...
