b.  Semiconductor "lasers", as follows:

Note 1:     6A005.b. includes semiconductor
                 "lasers" having optical output connectors (e.g.,
                 fiber optic pigtails).

     Note 2:     The control status of
                 semiconductor "lasers" specially designed for
                 other equipment is determined by the control status
                 of the other equipment.

     b.1.  Individual single-transverse mode
           semiconductor "lasers" having any of the
           following:

          b.1.a.  A wavelength equal to or less than
                  1510 nm, and having an average or CW output
                  power exceeding 1.5 W; or

          b.1.b. A wavelength greater than 1510nm, 
                 and having an average or CW output power
                 exceeding 500 mW;

     b.2.  Individual, multiple-transverse mode
           semiconductor "lasers" , having any of the
           following:

          b.2.a.   A wavelength of less than 1400 nm, 
                   and having an average or CW output power
                   exceeding 10W;

          b.2.b.  A wavelength equal to or greater
                  than 1400 nm and less than 1900 nm, and having
                  an average or CW output power exceeding 2.5 W;
                  or

          b.2.c.  A wavelength equal to or greater
                  than 1900 nm and having an average or CW
                  output power exceeding 1 W.

     b.3.  Individual semiconductor "laser"arrays,
           having any of the following:

          b.3.a.  A wavelength of less than 1400 nm
                  and having an average or CW output power
                  exceeding 80 W; or
     
          b.3.b.  A wavelength equal to or greater
                  than 1400 nm and less than 1900 nm, and
                  having an average or CW output power exceeding
                  25 W; or

          b.3.c.  A wavelength equal to or greater
                  than 1900 nm, and having an average or CW
                  output power exceeding 10 W.

     b.4.     Array stacks of semiconductor
              "lasers" containing at least one array that is
              controlled under 6A005.b.3.

     Technical Notes:  

     1.  Semiconductor "lasers" are commonly
         called "laser" diodes.

     2.  An 'array' consists of multiple
         semiconductor "laser" emitters fabricated as a
         single chip so that the centers of the emitted light
         beams are on parallel paths.

     3.  An 'array stack' is fabricated by stacking,
         or otherwise assembling, 'arrays' so that the
         centers of the emitted light beams are on parallel
         paths.
