GaN-Based High-Output-Power Blue Laser Diodes
Abstract
We succeeded fabricating high-output-power blue (445nm) laser diodes (LDs) with an output power of 500mW. The operating current, voltage, wall-plug efficiency of these LDs were 480mA, 4.8V, and 21.7%. Estimated lifetime of these LDs was over 30,000 hours under continuous wave operation at 25°C.
