White Papers and Case Studies

  1. 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.

  2. Robots, Lasers, And Artificial Intelligence Join Forces Undersea
    4/1/2019

    Subsea robots, lasers, and artificial intelligence have been combined into one dynamic solution that will change the methods of working underwater. The SeaVision® subsea 3D laser imaging system is used to perform high-resolution RGB laser line scanning. 

  3. 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. 

  4. The Race To The Starting Line: Edge-Emitting Diode Lasers vs. VCSELs For The Automotive Lidar Market
    3/13/2018

    The competition to be the leading diode laser source for automotive lidar is not a race to the top, but rather a race to the starting line. Before reaching the goal to implement lidar ADAS in consumer vehicles by 2020, there must be at least one year of certification and testing before going to market. 

  5. Achieving Standardized Measurements With BeamWatch AM
    12/1/2017

    The BeamWatch AM is Ophir-Spiricon’s beam monitoring system designed specifically for use in the additive manufacturing industry to provide non-interfering real-time beam measurement at the location of the working plane. 

  6. Creating A Passive Laser Beam Analyzer Through A Haas Laser Technologies And Xenics Partnership
    10/13/2017

    High power CO2 lasers produce a beam of infrared light with wavelengths centering typically at 9.3 or 10.6 μm. Haas Laser Technologies, Inc. has developed a compact, all passive optical design laser beam analyzer for focused laser beams from a CO2 laser with wavelength range from 9.3 to 10.6 μm. In conjunction with a Fabry-Perot resonator and Xenics’ Gobi-640-GigE microbolometer camera, the new beam analyzer offers laser beam measurement and analysis for continuous-wave (CW) as well as pulsed lasers.

  7. Which Industrial Cutting Method Is Right For You?
    3/28/2017

    Some applications require one specific type of cutting method and the other two methods are out of the question. This application note presents the process of each industrial cutting method, and comparisons between laser cutting, water jets, and mechanical cutting.

  8. Intro To Laser Management: Laser Profiling 101
    1/25/2017

    Traditionally, laser operators only verify a laser’s average power or energy to improve efficiency and, if everything is in order, put their laser back into service. This article discusses steps required to identify and use a camera profiling system (arrayed camera, attenuator, and beam dump) for laser management.

  9. Reducing Production Waste With Laser Profiling And Characterization
    1/25/2017

    A critical component in a laser manufacturing process is the understanding of which process parameters or key control characteristics must be measured and how they will relate to product quality and waste. A laser profiling system can be a great benefit for characterizing and identifying which variables affect product quality and waste minimization. Unfortunately, many companies realize this too late and incur more expenses and extended downtime than necessary when trying to implement the system near the end of the process. This article dives into a method of using in-house tools, like laser profiling, to characterize and optimize a process in advance so that product quality and process variability may be understood and maintained.

  10. Project Overview And Passive Component Development: Integrated Disruptive Components For 2µm Fiber Lasers (ISLA)
    1/18/2017

    The ISLA project was a research and development project with the goal of developing “building block” components of compatible and self-consistent active and passive fibers, fused fiber couplers and combiners, fiber-coupled isolators, modulators and high power pump laser diodes. This project also intended to develop a CW, a pulsed and a short pulse laser demonstration laser for use in applications testing. This paper delivers an overview of the project, the results from Gooch & Housego’s work on developing passive components for 2 µm fiber lasers, and the research efforts on different isolator materials with the largest Verdet constants to be used in 2 µm isolators.
