Abstract
980nm broad area diode lasers with stripe widths in the 90-100 μm range are commercially important as pumps for fiber lasers, as well as for direct applications [1]. Recent work on 910-990nm sources has shown that peak continuous wave (CW) powers in the 20-25W range are achievable in such structures [2,3] and reliable operation for > 4000 hours was reported at 20W [4]. Further improvements in peak reliable power and beam quality of diode laser sources are required to enable greater brightness from the overall laser system.
