71W at 59% efficiency continuous wave, from a single edge-emitter with 1000 µm aperture: the best combination of optical output power and conversion efficiency achieved to date from a single diode laser. The results were delivered from a diode laser on a compact, passively cooled heatsink with just one p-n junction. Far field remained in a range useful for industrial processing. Do check out the new paper from Seval Arslan and the high power diode laser team at the Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik, available now from the IEEE Photonics Society Journal Photonics Technology Letters.
