Abstract:
1. An improved method of fabricating a diode laser array, said array comprising a stack of at least three diode laser bars each thereof having a fast axis and a slow axis, the diode laser bars being directly bonded to each other one above the other in the fast axis direction, said array further including first and second cooling members in thermal contact with the diode laser bar stack at respectively the top and bottom thereof, said method comprises the steps of: determining the nominal emission wavelength of a plurality of diode laser bars; and: selecting particular nominal emission wavelength bars and positioning the selected bars in a particular order in the stack, said order being based on (a) the determined nominal emission wavelength of the bars and (b) the location of the bars with respect to the cooling members in order to tailor the shape of the aggregate emission spectrum and minimize the affects of temperature variations during operation.
