Multi-axis knife edge scanning laser beam profiler extended to measurements of M²
M2Beam-Laser Beam Analysis
The M² Beam provides analytical and graphical capability to measure the 2 axis M² figure of merit waist size and location of CW lasers. The M² factor is measured in accordance with the proposed ISO/CD 11 146.
Additionaly, the instrument measures the profile width, position and power of the laser beam at intersection points along the beam propagation axis.
The M² Measurement system is used with a Super BeamAlyzer™ head and a Stand Alone unit.
Measurements
- Beam Propagation (M²)
- Beam Waist Location
- Beam Waist Diameter
- Divergence
- Rayleigh Range
- Waist Asymmetry
- Astigmatism
