Laser analyzer gets M-square in 20 s

For quantitative measurement and viewing of high power CO2 laser beams, The NanoModeScan M2 laser beam propagation analyzer can measure an M2 -quality factor in as little as 20 s using either the ISO 11146 or Rayleigh method. The system is easily set up and aligned; the straight-line-of-sight design needs little or no attenuation.

The system can also report beam waist diameter and location, divergence, and a beam’s Rayleigh range for each axis. The instrument’s ease of use and update rate of up to 20 Hz suit it for CO2-laser-based material processing, machining, and marking applications where laser performance needs to be adjusted in real time. Both 200- and 400-mm lenses are available to generate the correct artificial waist for the laser source under test. (Contact Gary Wagner for pricing — available now.)
