The II-VI Laser Enterprise BLM 80W and 120W at 9xxnm and 10xxnm wavelengths laser diode Bar on Long passive Mini-cooler series has been designed to provide the increased brightness and reliability required for collimated pumping of next generation solid-state lasers and direct applications. The innovative small footprint design, 12.6mm by 24.8mm only, is enabling compact and light weight laser systems.

Thermal and electrical connection is possible by mechanical means (no soldering or wire bonding required). Mounting to a cold plate is easily achieved by pressing down the device with a stamp or using screws. For current connection leads or bus bars (recommended for >100A) can be used.

The proprietary E2 front mirror passivation process, developed at our Zurich site, prevents Catastrophic Optical Damage (COD) to the laser diode facet even at extremely high output powers. The laser diode bars are mounted on an expansion matched sub-mount onto a conductive cooled Cu block package providing very high reliability in CW and pulsed (1-Hz type) applications.
