Setting the Right Capture Block
Beam Profiling Concepts |June 20, 2016
Centering the laser beam and properly sizing the capture block are important steps in taking accurate laser beam measurements with DataRay software. In this blog post we explain why the beam needs to be centered on the capture block, and the errors that can occur if the corners of the capture block are illuminated by the beam.
Interfacing MATLAB with DataRay Beam Profilers
Interfacing |June 6, 2016
We are proud to announce a new tutorial on interfacing MATLAB with our beam profilers. An interface to MATLAB is useful given the variety of data processing toolboxes MATLAB provides.
Major Software Update & CLEO Conference 2016
DataRay Software |May 26, 2016
In this post, we discuss our major new software update, as well as provide a preview of the demos we'll be showing at CLEO Conference 2016
Systematic Error in ISO 11146 Measurements
Beam Profiling Concepts |May 12, 2016
Systematic error is an important calculation in any measurement system, and especially in ISO 11146 laser beam profiling measurements. In this blog post, we address the systematic error inherent to the measurement of beam width as laid out in the ISO 11146 standard.
M² and High-order Modes
M Squared |April 27, 2016
M² is a measurement that was originally designed to determine the quality of a real beam in comparison to a theoretically perfect fundamental mode Gaussian beam (Siegman 1990). Although many lasers are designed to output a fundamental mode Gaussian beam, imperfections and/or cavity design in the laser will often cause superimposed higher-order transverse modes.
M² Measurement
M Squared |April 12, 2016
As leaders in the laser beam profiling business, we have worked with M² for decades. In this blog post we discuss M², when to use it, and the way it is measured.
