Notes
Notes: 1. Pulsed “lasers” include those that run in a continuous wave (CW) mode with pulses superimposed. 2. Excimer, semiconductor, chemical, CO, CO2, and 'non-repetitive pulsed' Nd:glass “lasers” are only specified by 6A005.d.
Technical Note: For the purposes of 6A005 Note 2, 'non-repetitive pulsed' refers to “lasers” that produce either a single output pulse or that have a time interval between pulses exceeding one minute. 3. 6A005 includes fiber “lasers”. 4. The control status of “lasers” incorporating frequency conversion (i.e., wavelength change) by means other than one “laser” pumping another “laser” is determined by applying the control parameters for both the output of the source “laser” and the frequency-converted optical output. 5. 6A005 does not control “lasers” as follows: a. Ruby with output energy below 20 J; b. Nitrogen; c. Krypton. 6. For the purposes of 6A005.a and 6A005.b, 'single transverse mode' refers to “lasers” with a beam profile having an M2-factor of less than 1.3, while 'multiple transverse mode' refers to “lasers” with a beam profile having an M2-factor of 1.3 or higher
Note: 6A005.a.2 does not control Argon “lasers” having an output power equal to or less than 50 W.
Note 1: 6A005.a.6.b does not control 'multiple transverse mode', industrial “lasers” with output power exceeding 2 kW and not exceeding 6 kW with a total mass greater than 1,200 kg.

Technical Note: For the purposes of 6A005.d.5.c, 'transfer lasers' are “lasers” in which the lasing species are excited through the transfer of energy by collision of a non-lasing atom or molecule with a lasing atom or molecule species.
Technical Note: For the purposes of 6A005.e.1, 'active cooling' is a cooling technique for optical “components” using flowing fluids within the subsurface (nominally less than 1 mm below the optical surface) of the optical component to remove heat from the optic.
