White Papers and Case Studies

  1. 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.

  2. 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.

  3. 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.

  4. 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. 

  5. Frequency Comb Research Advances Using Tunable Diode Lasers

    The discovery of the optical frequency comb and the breakthrough work of Hänsch and Hall in refining the frequency comb technique have revolutionized the field of scientific metrology. In this application note, we will look more closely at how the so-called “microcombs” are generated and what the role of external cavity diode lasers (ECDLs) is in the microcomb generation process. We will briefly discuss how the microcomb is evolving into a compact, versatile tool with increasing application, for example, in the field of molecular spectroscopy. Although still maturing, the field of microcombs has the potential to transform various other disciplines, leading to compact comb generation platforms with numerous applications.

  6. Comparing Fiber-Coupled And Free-Space Lasers For Projection Applications

    This white paper compares the use of fiber-coupled and free-space lasers in projection applications.

  7. Tutorial: Modifying Laser Beams – No Way Around It, So Here's How

    This app note discusses how to match an appropriate laser beam profiling technique - such as building an aligned optical system, collimation and focusing, high power laser quality measurements, and proper attenuation design - to a laser application.

  8. Laser Source for Gas Sensing: Application Note

    This Mid-IR laser source’s compact size, robustness, spectral flexibility, and low power consumption makes it ideal for applications involving molecular spectroscopy. This application note offers information on how it can be used for gas sensing.
