Abstract

We report a study investigating the power scaling properties of a single gain chip GaInNAs/GaAs semiconductor disk laser emitting around 1180 nm. The power scaling was done by varying the pump spot diameter between 320 μm and 460 μm. The emission efficiency was assessed for output coupling ratios between 0.1% and 3%. A maximum output power of 11 W was achieved with a 1.5 % output coupling ratio and a pump spot diameter of 390 μm. The heat from the active region was extracted by an intracavity diamond heat spreader attached to a water-cooled copper mount.
