M2 Beam High Power-Beam Profilers

This is a software driver device that interfaces to any host PC computer, running under Windows Vista/XP/2000/7 (32 & 64 bit), via USB port.

Latest versions of Duma’s M² Laser Beam Propagation Analyzer offers the maximum flexibility and superior capabilities of measurement of pulsed or CW beams, from UV to wavelengths over 1.6 microns.

Two versions are offered:

1) Multi-axis knife edge scanning sensor with folded cavity.

2) Camera based sensor using a similar folded cavity. Specially designed for pulsed lasers or CW beams.

  • Beam sizes up to 25 mm
  • Wavelengths up to 2.7 microns
  • Determination of M², waist location and waist diameter.
  • Low & high power laser beams measurement.
  • Up to 4 kWatts.
  • In accordance with latest relevant ISO standards.
