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).

* * * * *

[[Page 30539]]

    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 [micro]s and an 
output energy exceeding 50 J per pulse; or
    d.6.b. A ``pulse duration'' exceeding 1 [micro]s 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 [micro]rad;
    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 [micro]m, 
whichever is the smaller;
    f.4. Projection telescopes specially designed for use with 
``SHPL'' systems.
