how do you rate output laser power?

The output power is the maximum power value at the exit of the laser housing.  All our lasers have their power rated after passing through the optical assemblies.  The power is measured according to CDRH specifications.

  Each laser is classified by measuring the amount of optical power that would enter a 7 mm aperture that is located at a distance of 20 cm from the laser source.  Our line lasers have a lower classification rating because the laser power is spread along the length of the line.
