Abstract

Fiber coupled light output power of highly reliable single mode laser diodes with an emission wavelength of around 980 nm has been increased by 40% as compared to former results. The devices reach in excess of 1.3 W ex-facet CW light output power with up to 60% power conversion efficiency and exhibit a vertical far-field of around 21°. The maximum fiber coupled CW light output power amounts to more than 700 mW. The devices are designed to satisfy the stringent requirements of future cost efficient uncooled applications as well as the high power market of broadband multi channel networks.
