Viewing Beam Profiling Concepts
Pulsed Lasers and External Trigger Mode
Pulsed Lasers |December 2, 2016
This is the second entry in a series of blog posts that explore DataRay’s pulsed laser measurement capabilities. This blog post will now talk about how an external trigger can be used to formally synchronize the exposure time to the pulse width. This External Trigger mode provides more versatile and precise measurements of pulsed lasers.
Pulsed Lasers and Auto-Trigger Mode
Pulsed Lasers |November 21, 2016
This is the first entry in a series of blog posts that explore DataRay’s pulsed laser measurement capabilities. This blog post will review how capturing pulsed lasers with a camera beam profiler differs from capturing CW lasers, and how the additional challenges with pulsed lasers are handled to provide useful measurements with the software’s Auto-Trigger mode.
When to Use the D86 Beam Width Measurement Method
Beam Profiling Concepts |September 15, 2016
Although the clip level method and the second moment method are the most popular methods of beam width measurement, other beam width measurement techniques such as the D86 method can be used with beam profiling cameras.
Scanning Slits vs. Cameras
Beam Profiling Concepts |August 4, 2016
Our customers often ask us what type of beam profiler they should use to measure their laser beam(s). In this blog post, we explain the relative advantages and disadvantages of a scanning slit profiler and a camera-based profiler.
Why We Tilt Our Filters
Beam Profiling Cameras |July 21, 2016
In this blog post, we explain why tilting our filters is necessary for an accurate beam measurement.
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.
