Abstract

Based on minimum spot condition, a method for laser beam quality measurement is proposed. From beam diameter measurements at two locations along laser beam propagation axis, location of beam waist, waist width, far-field divergence angle and M² factor can be given.
- beam quality,
- M² factor
