    4/1/2016

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

  2. Beam Diagnostics Improve Laser Heat Treatment Effectiveness
    4/1/2016

    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.

  3. High Power Industrial Laser Applications: New Solutions To Old Problems
    4/1/2016

    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
    4/1/2016

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

    As the high power laser market continues to grow, demands for effective high power laser measurement tools have also increased. In response to the various needs of each segment of the high power laser market, Ophir has developed the BeamWatch tool that covers as many of these requirements as possible. Since high power lasers in excess of 1 kW generate enough Raleigh scatter to be detected by silicon based sensor arrays, a lens and camera system in an off-axis position can be used as a non-contact diagnostic tool. This article discusses the technical challenges and solutions encountered in the development of the BeamWatch measuring instrument.

  6. 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.

  7. 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.

  8. 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. 

  9. 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.
