BeamWatch utilizes disruptive technology to measure laser beam characteristics of very high power lasers. By not intercepting the beam and yet providing instantaneous measurements, you can now monitor the beam at frequent intervals without having to shut down the process or remove tooling and fixtures to get access. In addition, you can now measure focal spot location at several times per second and know if there is any focal spot shift during those critical start-up moments.

Disruptive Technology

BeamWatch is the first device to measure a laser without coming in contact with its beam which allows it to be the first laser quality measurement product in history to have no upper limit on the lasers which it can measure. BeamWatch provides high-power industrial laser users with data never before seen such as the dynamic measurement of focus shift caused by thermal effects on the laser system. BeamWatch also provides the industrial laser user with measurement of other key laser operating parameters in real-time.

The system measures the signal generated from Rayleigh scattering around the laser’s beam waist, where the power density is the highest. Rayleigh scattering is a physical property of light caused by light scattering off of air molecules. Unlike traditional beam measurement systems, the beam passes directly through BeamWatch and is not disrupted, mechanically or optically. In addition, BeamWatch has no moving parts so there is no need for cooling of any components. Specialized system software dynamically measures the signal multiple times per second, allowing the laser user to key in on critical operational laser attributes, such as beam waist size and position with respect to the material being processed.

BeamWatch User Interface

The user has access to those tools needed for start-up and
advanced beam diagnostics.

Focus Spot Size (Waist Width)

BeamWatch images the full beam caustic measuring the waist at its smallest point, many times per second.

Focus Spot Location

Now you can precisely know the dynamic behavior of focal spot shift throughout the laser duty cycle. By inputting the known distance from the laser delivery head to a precise datum on BeamWatch the focal spot distance is constantly measured and tracked with millisecond updates.

Assured Process Consistency

Measure as often as needed to assure repeatable and consistent process uniformity. Mount BeamWatch into the process or manually insert BeamWatch and make periodic measurements.
You can also automatically compare to initial process validation measurements and utilize automated pass/fail.

Automation Interface

BeamWatch includes the tools to support Automation Clients written in Visual Basic for Applications (VBA), C++ CLI, or any .Net compliant environment, such as Microsoft Excel or National Instruments’ LabVIEW.

Measuring Focal Shift with BeamWatch		Focus Shift Monitoring of High Power Laser

Is your laser's focus spot where you think it is? This video shows the focal shift of a 100 Kw laser during the first four seconds of startup using BeamWatch, Ophir's non-contact high power beam analyzer.		BeamWatch™ utilizes disruptive technology to measure very high power YAG and fiber lasers. By not intercepting the beam and yet providing instantaneous measurements, you can now monitor the beam characteristic at frequent intervals without having to shut down the process or remove tooling and fixtures to get access. In addition, you can now measure focal spot location at millisecond intervals and know if there is any focal spot shift during those critical start-up moments.

BeamWatch Dynamically Measures 100kW Fiber Laser		Laser Measurement Solutions for High Power Industrial Laser Applications

The BeamWatch® industrial beam profiling system provides data that has never been seen or measured, even to laser users that have been working with high-power lasers for years. Through the dynamic measurement of beam waist location, the laser engineer can know how changes in power density affect the quality the process. For example, data is now available about the laser’s effect on the quality and consistency of laser welds, cuts, and holes drilled.		Modern production facilities must constantly increase throughput, at less cost, with less scrap, and with minimum downtime. In this video overview, you will learn how application of new, advanced technology in measurement devices, can help both designers and users of industrial laser systems to optimize and control their processes, so they can accomplish these goals and achieve consistently good results – both in quality and quantity.
