CFR Correction

In Title 15 of the Code of Federal Regulations, Parts 300 to 799, revised as of January 1, 2011, on page 802, in Supplement No. 1 to Part 774, in Category 6, in ECCN 6A005, the following text is reinstated at the end of the entry:

6A005 “Lasers” (other than those described in 0B001.g.5 or .h.6), components and optical equipment, as follows (see List of Items Controlled).

* * * * *

Items:

* * * * *

d.5. “Chemical lasers”, as follows:

d.5.a. Hydrogen Fluoride (HF) “lasers”;

d.5.b. Deuterium Fluoride (DF) “lasers”;

d.5.c. “Transfer lasers”, as follows:

d.5.c.1. Oxygen Iodine (O2-I) “lasers”;

d.5.c.2. Deuterium Fluoride-Carbon dioxide (DF-CO2) “lasers”;

d.6. “Non-repetitive pulsed” Neodymium (Nd) glass “lasers”, having any of the following:

d.6.a. A “pulse duration” not exceeding 1 µs and an output energy exceeding 50 J per pulse; or

d.6.b. A “pulse duration” exceeding 1 µs and an output energy exceeding 100 J per pulse;

NOTE: “Non-repetitive pulsed” refers to “lasers” that produce either a single output pulse or that have a time interval between pulses exceeding one minute.

e. Components, as follows:

e.1. Mirrors cooled either by active cooling or by heat pipe cooling; Technical Note: 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.

e.2. Optical mirrors or transmissive or partially transmissive optical or electro-optical components specially designed for use with controlled “lasers”;

f. Optical equipment, as follows:

N.B.: For shared aperture optical elements, capable of operating in “Super-High Power Laser” (“SHPL”) applications, see the U.S. Munitions List (22 CFR part 121).

f.1. Dynamic wavefront (phase) measuring equipment capable of mapping at least 50 positions on a beam wavefront having any the following:

f.1.a. Frame rates equal to or more than 100 Hz and phase discrimination of at least 5% of the beam's wavelength; or

f.1.b. Frame rates equal to or more than 1,000 Hz and phase discrimination of at least 20% of the beam's wavelength;

f.2. “Laser” diagnostic equipment capable of measuring “SHPL” system angular beam steering errors of equal to or less than 10 µrad;

f.3. Optical equipment and components specially designed for a phased-array “SHPL” system for coherent beam combination to an accuracy of lambda/10 at the designed wavelength, or 0.1 µm, whichever is the smaller;

f.4. Projection telescopes specially designed for use with “SHPL” systems.
