Abstract
Thermal management may in some cases improve the optical output of a semiconductor laser diode array. For example, providing gaps such as air gaps, at suitable locations may influence the temperature distribution of laser diodes in a laser diode array and curtail thermal lensing, which may in turn decrease beam divergence and increase delivered power.
