BeamWatch is our full-function software with an extensive set of ISO quantitative propagation measurements, NIST calibrated power measurements, graphical representations of the beam caustic. Requires user supplied PC.
Software
BeamWatch AM provides simultaneous measurements of multiple profiles along the beam caustic in the camera field-of-view (FOV). Real-time measurements are performed at video rates.
They include:
• Waist (focus spot) width and location
• Focal shift
• Centroid
• M2 or K
• Divergence
• Beam Parameter Product
• Rayleigh length
• Absolute power
• Tilt angle
Real-time performance also allows for measurement of dynamic focal shift during laser startup. BeamWatch AM measurement technique is based on Rayleigh scattering of laser light by oxygen and nitrogen molecules in the air as the beam propagates through the medium. Measurement of this scattered light provides an equivalent slit-scan of the laser beam in the direction of the observed view. The scattered light is measured using a conventional camera and image capture systems. BeamWatch AM includes a camera for spatial measurements and a NIST-traceable power sensor that will provide a complete analysis of the laser power density profile. The camera is simultaneously, and real-time, viewing the beam caustic including the near/ focus/and far field of the beam. This measurement technique includes Propagation and M2 measurements adhering to the ISO 11146 standards.
In addition, and because all measurements are made in real-time, any focal shift occurring during the critical start up seconds is measured and reported. BeamWatch AM has USB connectivity to Windows personal computers for data acquisition, analysis, and display.
