Abstract
An array of laser diodes, or laser diode bars, is formed by positioning adjacent diodes or bars in an offset or staircase arrangement where the emitting facets of adjacent diodes, or bars, are in different planes. The offset arrangement permits the light from adjacent facets to be separated a distance q much shorter than permitted by prior art stacking arrangements because thermal and mechanical constraints characteristic of prior art stacks, are relaxed considerably in the offset arrangement. Power densities of 2000 watts/cm.sup.2 (cw) are achieved with spacings of 0.6 mm between adjacent laser bars, a ten fold increase in power density over in-plane (prior art) positioning of like components.
