Abstract

We have developed a 'FUNRYU' water cooled heat sink to efficiently cool the LDs and a new assembling system to reliably fabricate LD arrays and evaluated them using a conventional AlGaAs LD bar. We have achieved a maximum CW output power of 115 W limited by the driver circuit and the maximum conversion efficiency of 51% furthermore, we also design the 'FUNRYU' heat sink to be stackable and obtained a power density over 550 W/cm².
