Why and How to Profile Challenging Laser Applications
We introduce three techniques for monitoring the critical characteristics of the beam as the laser is used in three very different applications: (a) VSCEL / Laser Diode Mode and beam divergence, (b) Additive Manufacturing lasers used is 3D SLM / SLS, and (c) Fiber welding / heat treating / cleaning lasers. We will discuss three…

Things to Remember When Setting Up Laser Measurement Equipment for the First Time
Recently, I had the opportunity to perform a product demonstration for a prospect. I’d been in field sales for Ophir for about seven and a half years from 2009 to 2016, but with the pandemic limiting customer visits over the past several years combined with a recent role change, it had been a while since…

Terahertz Technology- New Challenges, New Solutions
Terahertz (=THz) radiation is electromagnetic radiation located between the low-frequency far-infrared and the high-frequency microwave parts of the spectrum (from 0.3 to 3 x 1012 Hz, with a wavelength from 10 micrometers to 1 mm). THz radiation is unique because it combines useful properties of both radio waves and infrared waves. THz radiation can be…

The Focal Length Divergence Measurement Method
The Focal Length Divergence measurement method is based upon the beam width of a focused beam’s spot size and the focal length of the focusing optic. The Focal Length Divergence method provides a means for finding the far-field beam divergence at any point in the beam propagation path. As shown below, the calculation performed by the BeamGage® software…

Maintain Proper Laser Beam Parameters for Additive Manufacturing
Additive manufacturing (AM), including selective laser melting (SLM) and 3D printing, relies on its laser source to properly manufacture 3D-printed parts. The laser is at once the most essential element of the system, and the most vulnerable to degradation. Here are some of the malfunctions that can occur with an unmonitored laser system: Optical pass…

Blooming and Smearing in Your Beam Profile? Why It Happens and How to Fix It
When measuring your laser beam profile, you expect the measurement to be accurate, so it can be frustrating to see artifacts that are clearly not right. Before discussing how to fix it, or even when and why it happens, let’s explain what exactly bloom and smear are. What do blooming and smearing look like? Bloom…
