Tunable semiconductor ‘lasers’ and tunable semiconductor ‘laser’ arrays, other than those specified in 0B001.h.6. or 6A005.b., of a wavelength between 9 μm and 17 μm, as well as array stacks of semiconductor ‘lasers’ containing at least one tunable semiconductor ‘laser’ array of such wavelength. Note : Semiconductor ‘lasers’ are commonly called ‘laser’ diodes.
