Characterizing A Laser Used In Metal Additive Manufacturing Equipment
7/30/2020
In this application note, a developer of power-bed additive manufacturing systems needed a beam profiling system that could be used by their field technicians for setup and maintenance of customers’ lasers. The bulky water-cooled system they had been using was costly, and long lead times for sale and repair were unreasonable. Moving to a BeamGage® based system made setup quick and finding the focal spot location easy.

Introduction to Quad Laser Position Sensing Detectors And Monitor
7/9/2020
The Gentec-EO QUAD-4Track takes advantage of the superior performance of their Pyroelectric Quadrant Detectors over Silicon quad and lateral effect photodiodes. These QUAD-E detectors are designed to measure pulsed lasers and QUAD-P detectors for CW or Quasi-CW lasers. The QUAD- 4Track Laser Position Monitor is a powerful, 4-channel, microprocessor-based instrument that not only measures beam position, but also the power or energy of the laser. This application note provides a basic overview of these products and their capabilities.
