High-power and narrow vertical divergence angle 980nm InGaAs/AlGaAs quantum well semiconductor lasers have important applications in optical fiber communications, medical and military fields and so on. Traditional semiconductor laser is difficult for obtaining satisfactory power output and beam quality simultaneously. Large optical cavity 980nm high power semiconductor laser (PBC-HPLDs) with one-dimensional...
A new class of semiconductor laser named slab-coupled optical waveguide laser (SCOWL) that appears several advantages of single mode and high output power has been investigated. The 808-nm SCOWL device we have designed was based on AlGaAs-GaAs material system. We have introduced the slab-coupled waveguide concept and combined it with the multi-quantum technology. Then we simulated the structure with...
The high power laser diode bars have many advantages over conventional lasers of similar power levels. However, the poor beam quality of its output beam hinders its direct applications. The technologies for beam shaping of the high power laser diode bars have become a hot topic. In this paper the applications and the progress of high power high brightness fiber coupled laser diode are discussed.
