Abstract

A laser diode array has laser diode strips divided into groups which are separated from one another by zones having a damping or attenuation effect for radiation generated in the diodes. A maximum number of laser diode strips provided within each group is determined such that super radiation or oscillatory mode radiation generated within the groups and which deviates from a primary radiating direction of strips within the groups is negligible.
