COD-free high power (760 mW) 980 nm laser diodes with current-blocking facets

A buried ridge 980 nm InGaAs-GaAs double QW laser diode (LD) with current-blocking facets has demonstrated catastrophic optical damage (COD)-free maximum output power of 760 mW and linear power over 500 mW. The LDs show the same light output characteristics even after 1600 hours aging at 300 mW and 50/spl deg/C.
