High Power Laser Diode and Application

摘要

We have developed FUNRYU water cooled heat sink and new assembly system. We evaluated the cooling characteristics of the heat sink and reliability of the assembly system using a Al free LD bar. We confirmed their noble performance. From a preliminary experiment using a new material composition with InGaAsP, we have attained CW operation over 200 W and the efficiency over 50% from a 1 cm bar. By using these high performance laser diode array, we have achieved a maximum CW output power of 1.014 kW for fiber embedded disk laser (at HOYA corporation).
