Summary

Description
English: The maximal allowed cw-powers for the laser classes 1, 2, 3R and 3B according to the norm EN 60825-1:2007. Note that these values hold only for static, point-like laser sources (i.e. collimated or weakly divergent laser beams), for extended or strongly divergent laser sources the powers can be larger.

Some missing and some numerical values:

  • 180 nm < λ < 315 nm: for laser class 1 and 3R the limitations are just defined in terms of pulse energy.
  • 500 nm < λ < 700 nm: P < 0.39 mW for laser class 1 and P < 5 mW for class 3R and 500 mW for class 3B.
  • 1700 nm < λ < 4000 nm: the limiting powers are equal to those at λ = 1700 nm.
