Abstract
In this paper we report a 980 nm InGaAs/GaAs MQW semiconductor laser array. The epilayer structures are grown by MBE. We have fabricated broad areas lasers with a cavity length of 1000micron and a stripe width of 6micron and a stripe spacing of 100micron. The measurements are performed in quasi-continuous wave mode (QCW). The highest QCW output power of 12W for laser array with coated facets is achieved. The threshold current density is 400 A/cm2 at 15degree. The slope efficiency is 0.74W/A. The lasing spectrum is peaked at 979.4 nm with a FWHM of 3nm.
