Abstract
It is demonstrated that substantial operating-parameter-dependent temperature-differences can exist between diode-laser bars in pulsed operation of a stack of such bars arranged to provide a two-dimensional array of diode-laser emitters. These differences can produce distortion of the aggregate output spectrum of the stack. By selecting particular nominal emitting wavelengths of the diode-laser bars for specific positions in the stack, the aggregate emission-spectrum can be tailored to a desired shape for one or more sets of operating parameters of the stack.
