II-VI Incorporated announced the introduction of 170 W passively cooled and 250 W actively cooled laser bars. II-VI’s new passively and actively cooled laser bars enable high efficiency coupling into optical fibers due to their excellent mechanical flatness properties or 'low smile'. They also feature a critical and proprietary hard solder technology which is designed to withstand the high power pulsed and on/off operation typical for direct diode lasers. Direct diode lasers used in industrial sheet metal cutting, welding and additive manufacturing are achieving up to tens of kilowatts of output power using wavelength and polarization multiplexing of multiple high power GaAs semiconductor laser bars.
