  1. Materials Processing: When Laser Measurements Absolutely, Positively Must Be Made

    In order to improve laser-based processes, a variety of parameters must be measured to understand how design changes effect performance, and how to help avoid component degradation. The challenge occurs when figuring the proper frequency of measurements throughout the life of the laser, choosing which measurements should be tracked, and what should be done with the collected data. There are five times within a laser system’s lifetime where the collection and application of laser performance measurement data are critical to the process’ outcome.

  2. Measuring Small-Beam MFD: Overcoming the Challenges

    Accurate beam size measurements for beam sizes under 10 μm are critical for many applications such as fiber optic coupling efficiency, defect scanning, optical design, and optical fabrication process control. The challenges for such a measurement include the use of focal plane arrays that are too large to reasonably profile without magnification, the high mechanical precision of the beam profiling apparatus, and the beams’ high divergences and rapid expansion. Reliable profiles for such small beams, however, can be obtained using near-field or far-field profiling techniques. This article presents and in-depth discussion of each technique, diagrams for their systems' set-up, and the benefits for using each one.

  3. Additive Manufacturing And 3D CAD

    This article discusses the process of transforming a 3D CAD model into a mechanical component, as well as how to use a camera based beam profiling system to assist in achieving consistently accurate constructs.

  4. Select The Right Laser Power Sensor By Asking The Right Questions

    When a sensor turns out to be an incorrect choice, the system could procure inaccurate measurements, premature failure, and costly full disc replacement and recalibration. This article presents three critical questions to ask before selecting a laser power sensor for a specific application.

  5. Reimaging UV Laser Beam Profiling

    Ophir-Spiricon offers three families of UV converter products designed for the indirect measurements of UV laser beam profiles. This application notes compares and contrasts each family, and covers their basic specifications and applications.

  6. University Research Team Faces Challenges Of Measuring Multiple Lasers

    There are often times where several laser sources must be tested, validated, or qualified for a particular project. Unfortunately, by the time scientists realize that these measurements need to be made, the laser systems are typically already in place, the experiments are ready to be conducted, and any delays could be counterproductive. Therefore, laser measurement equipment needs to be cost effective, commercially available, easy to use, quick to set up, and operate at a high level of performance. This application note describes the challenges a university had in measuring three different lasers, and how they solved this problem with the Ophir-Spiricon XC-130 InGaAs beam profiling camera.

  7. Minimizing Corrosion In Water Cooled Sensors

    This article presents recommendations on minimizing corrosion that occurs in water cooled sensors.

  8. Beam Diagnostics Improve Laser Heat Treatment Effectiveness

    In order to get the highest quality heat treatments using lasers, it is important to understand the beam shape, the uniformity of the intensity, and the cleanliness of the delivery optics. This white paper discusses beam diagnostics with the use of Ophir’s BeamGage software used to improve results.

  9. High Power Industrial Laser Applications: New Solutions To Old Problems

    The advanced scalability, high beam quality, and wall-plug efficiency of fiber lasers in particular have made high-power lasers a common tool for commercial use. This paper discusses the concepts of proper monitoring and correctly defined laser parameters in industrial laser applications.

  10. Solving A Difficult Military Beam Alignment Task

    Laser systems used in the periscope of a nuclear-powered submarine providing on-board instrumentation that offers accurate pitch, yaw, and roll data. As a result of the critical nature of this information, the burden is placed on the quality of the laser beam, its size, its shape, and its intensity.
