    This article offers measurement considerations of disinfection methods based on UV radiation for fighting COVID-19 in the current pandemic.

34. Joined Fast Together: e-Mobility And Laser Welding In Automotive Production 9/2/2020

    The latest automotive manufacturing processes and e-mobility technologies are tightly linked to laser welding. This white paper explores the challenges found in this juncture and why the quality of the laser beam is so important.

35. Laser Measurements In Materials Processing: How And When They Absolutely, Positively Must Be Made 9/2/2020

    When improving laser-based processes, there are a variety of parameters that must be measured. Additionally, the continuously rising power of laser systems in material processing makes the requirements for laser measurement systems more challenging than ever. This white paper discusses laser measurements in materials processing as well as how and when they must be made for the best results.

36. Overcoming The Challenges Of Measuring High Power NIR Lasers 9/2/2020

    A variety of applications and production rates require periodic checkups or constant tracking of parameters, to ensure process control and quality assurance. Parameters to be tracked can include spot size, beam shape/mode, focusing position, M2, and laser power/energy. While laser power/energy can be measured by a conventional thermopile sensor with water cooling, other parameters such as spot size, beam shape, focal position, and M2 require more advanced techniques to measure high power laser parameters without distorting them or damaging the analytical equipment. This white paper discusses the challenges of measuring high power NIR lasers and presents a number of solutions to them.

37. How To Properly Select A Laser Power Or Energy Sensor 7/30/2020

    Selecting a sensor to accurately measure laser power or pulsed laser energy can seem like a simple procedure, but often, the selection process is limited to choosing a sensor that only meets the range of power or energy to be measured, leaving out other essential criteria. 

38. Measuring Very Low Power IR Lasers With The RM9 Radiometer System 7/30/2020

    There are two main technologies - thermal and photodiode - that are commonly used for measuring laser beam powers. But what if you need to measure very low power laser beams with wavelengths in the mid or far IR region. This article discusses a solution to fill this gap with the RM9 radiometer system.

39. Centauri High End Power/Energy Meter Experience – Now At The Tip Of Your Fingers! 7/30/2020

    Ophir Photonics introduces the Centauri Web simulator. Check out this article to learn more on how the simulator can allow you to experience most of the Centauri power/energy meter's functionalities.

40. 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.
