  1. Measuring Pulsed Lasers With NanoScan 2s

    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.

  2. A Discussion Of Laser Beam Profiling And The Subject Of Accuracy

    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.

  3. 5 Situations Where Laser Performance Measurement Is Necessary

    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. 

  4. Laser Ablation Makes Automotive Interiors Shine

    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.

  5. High Power Lasers In Medical Applications

    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. 

  6. LIDAR Guns, Accuracy, And Speeding Tickets

    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. 

  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. System Integration Of Fiber Lasers And Its Effects On Laser Quality

    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.

  9. Modifying Laser Beams 101 – No Way Around It, So Here's How

    In this article we will discuss how to match an appropriate laser beam profiling technique to a laser application. The discuussion includes building an aligned optical system, collimation and focusing, high power laser quality measurements, and proper attenuation techniques.

  10. Tutorial: The Importance Of CO2 Laser Optimization

    The New Year is a time to look back on the past year and contemplate on how to do things better. It’s a time to make New Year’s resolutions in an effort to be a better person. One of the most common and popular New Year’s resolutions is the renewed commitment to losing weight.  As many of us are all too familiar with, that means eating better and getting involved in a regular exercise routine. One of the advantages of losing weight in the 21st Century is the technology at our fingertips that helps us reach those goals. From the sciences behind how the body uses the food we eat, to the plethora of Smartphone apps that help us measure and track our results, it seems like losing weight would be an easy task. So why is it not? By John McCauley, Midwest Sales Manager, Ophir-Spiricon
