  1. Quality Assurance In Additive Production 3/17/2020

    Whether in research or in production, the laser parameters must be checked regularly. For this purpose, Fraunhofer Research Institution for Additive Manufacturing Technologies IAPT generally turns to the Ophir BeamWatch AM, which measures the laser beam without contact, is compact enough to be used inside the production chamber, and delivers measurement results quickly. This case study covers the full story.

  2. Measuring Average Power Of Pulsed Lasers With Photodiodes 3/17/2020

    Recent development in VCSELs for applications in remote sensing, require measurement of average power during pulsed operation. When measuring average power of pulsed lasers, another mechanism may also affect the linearity of the photodiode. In this article we review this mechanism.

  3. ISO Compliance Of Non-Contact, Real-Time Beam Analysis 8/1/2019

    To deliver continuously high product quality, the key parameters of laser beams in production applications must be measured on a regular basis. Ophir has tackled the task and developed a non-contact measurement technology, the BeamWatch, based on the Rayleigh scattering. 

  4. Battle Axe vs. Scalpel: How To Work With High Power Density Lasers 8/1/2019

    In this Q&A article, Mark Gitin, Senior VP and GM of the Light & Motion Division of MKS Instruments, and Christian Dini, Director Global Business Development, Ophir, discuss the use of reliable laser beam measurement technology that can help with the process of laser optimization.

  5. Understanding VCSEL Measurement Solutions 4/2/2019

    Vertical Cavity Surface Emitting Lasers (VCSELs) are a type of semiconductor laser diode. This article discusses VCSEL measurement solutions and how Ophir equipment can be used to get reliable power and beam profile data on VCSELs.

  6. Analyzing Small, High Power Beams At Focus In Manufacturing Applications 2/14/2019

    Lasers are increasingly deployed in manufacturing applications, being pushed to higher output powers and smaller beam sizes to work faster and with higher precision. Determining the beam profile at the beam focus of these lasers is critical to verify and improve manufacturing product quality. 

  7. Beam Profiling In The SWIR Range: What You Need To Know 10/26/2018

    Phosphor-coated CCD cameras have their place in gross beam alignment and applications where essential beam diagnostics are not required. This paper describes how phosphor cameras are wrong for accurate beam diagnostic measurements and discusses how InGaAs cameras excel in this area.
