High power 980nm pump laser diodes with decoupled confinement hetero-structure

700mW fiber-output was attained from a narrow-stripe InGaAs/AlGaAs decoupled confinement hetero-structure laser. The failure rate at 300mW-25deg.C was estimated to be 430FIT with 90% confidence level from the accelerated aging test of 1.4million device-hours.
