Abstract
High-power diode laser bars (DLBs) based on InGaAlAs quantum-confinement he terostructures with an output optical power of no less than 100 W in a quas i-continuous wave regime (pulse duration, 200-400 mus; repetition rate, 50- 100 Hz) were fabricated and investigated. A bar of this type consists of a set of strip emitters, each representing an optimized phase-locked array of single-mode emitters. This design provides for a considerably improved tem poral and spatial stability of the DLB emission, with a simultaneous decrea se in the optical noise level. (C) 2001 MAIK "Nauka/Interperiodica".
