Watch: Measuring Long-Wavelength Lasers

Using SWIR, MIR, and FIR lasers requires knowledge of their beam quality parameters. Numerous products and techniques have been developed to enable the measurement of beam quality parameters for long-wavelength light sources. In this webinar hosted by Photonics Spectra, Kevin Kirkham discusses the types of measurement tools that are available for long-wavelength sources — IR…

Watch: How Do You Know Your AM Laser is Performing to Spec?

How can you assure your AM laser is performing as needed to produce high quality, consistent builds? Some modern in-situ tools provide a partial picture of the performance of the lasers that are empowering your 3D laser printers, but they often don’t tell the complete story because they capture only a portion of the laser…

Watch: Controlling High-Power Laser Processes

Laser beams with powers of many tens of kilowatts are becoming increasingly common in today’s industrial applications. However, as the powers increase, the stakes increase as well. In this webinar, Mark Slutzki of Ophir discusses how to monitor appropriate laser parameters to keep high-power processes stable and predictable. * The webinar was produced by Photonics…

Watch: Laser Measurement Solutions for Material Micro Processing Applications

If you use lasers in material “micro processing” applications – such as drilling via holes in PCBs, OLED display “lift-off”, cutting of smartphone cover glass – you already know how difficult the challenges are. The often delicate combination of laser parameters – ultra short pulse duration, high repetition rate, perhaps short wavelength among others –…

Watch: Laser Measurement PC Interfaces

If all your laser measurement work involves a laptop or a PC, rather than a stand-alone meter, one of Ophir’s direct-to-PC interfaces could be an ideal solution. These are full-fledged Laser Power and Energy meters, but instead of having a separate on-board display, the PC becomes your display. In the following video you will learn…

Watch: Managing Laser Degradation in Industrial Applications

Lasers are made of physical matter. Therefore, the natural degradation of their materials can cause variability in performance. Aging optics often cause slow changes in laser behavior and, when left unchecked, these changes can lead to loss of process efficiency. An unclean process environment can quickly change a laser’s behavior through thermal lensing, which is…

Watch: How to Measure Low Power, Slowly Pulsing Beams (“Low Frequency Power”)

Are you trying to measure a low-power, slowly pulsing beam (think of a VCSEL beam for example) – and getting frustrated? Measuring low-power, slowly pulsing beams using photodiode sensors can be surprisingly tricky. Learn about the technical challenges you’ll face when trying to measure such beams, and about the Ophir solutions that will help you.…
