  1. Development Of A Non-Contact Diagnostic Tool For High Power Lasers
    3/29/2016

    This article discusses the technical challenges and solutions encountered in the development of the BeamWatch measuring instrument.

  2. Measuring Pulsed Lasers With NanoScan 2s
    11/23/2015

    The NanoScan 2s is a scanning slit, sensor-based, beam profiling system designed to profile pulsed laser beams with repetition rates in the 10 kHz range and above, and incorporate a “peak connect” algorithm to enable pulsed laser measurements. This application note discusses how the NanoScan 2s uses two modes of pulse operation for accurate beam profiling.

  3. A Discussion Of Laser Beam Profiling And The Subject Of Accuracy
    11/23/2015

    There is no calibration standard from which a camera system can be verified based on beam profiling measurement accuracy. The next best thing is to enhance the input (camera), and output (software algorithms) of the imaging system for improved precision and repeatable results. This application note discusses how to achieve beam profiling measurement accuracy without the use of a standard calibration method.

  4. 5 Situations Where Laser Performance Measurement Is Necessary
    11/20/2015

    Laser performance measurements can be accomplished through a number of techniques and can give laser users more relevant, time-based data that portrays trends in laser operation rather than single data points. 

  5. Laser Ablation Makes Automotive Interiors Shine
    6/30/2015

    This application note describes how JUNO, the F150A-BB-26 thermopile laser power sensor, and StarLab measurement software are used to know the status of automotive etching equipment in order to keep the power beam stable.

  6. High Power Lasers In Medical Applications
    6/25/2015

    The full list of medical procedures involving lasers is growing every day and, when discussing the development and production of medical devices, the importance of high power industrial lasers cannot be overlooked. 

  7. LIDAR Guns, Accuracy, And Speeding Tickets
    4/30/2015

    A Light Detection and Ranging (LIDAR) system uses a 130 μW 904 nm beam produced by three light emitting diodes (LEDs), and a telescope working together in order to calculate how long it takes for the beam to leave the device and return to the telescope. 

  8. Tutorial: Modifying Laser Beams – No Way Around It, So Here's How
    4/15/2015

    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.

  9. System Integration Of Fiber Lasers And Its Effects On Laser Quality
    11/10/2014

    Recently, companies that perform system integrations have become more concerned about the quality of the laser delivered to the process and not just the quality of the laser source itself. Some companies are now starting to use beam profiling for much more than simply qualifying the laser source. They also leverage the technology to qualify the components that are integrated into their systems and to characterize the application of the laser. Using sample beam profiles as illustrations, this article defines laser quality and provides examples of how laser system quality can be affected by system componentry.
