Power scaling of high efficiency optically pumped semiconductor disk laser

This paper is on power scaling of high power optically pumped semiconductor disk laser. It overcomes power limitation (watt level limitation) and offers the unique cw as well as ps-fs pulse operation and beam quality like solid state disk lasers. The OPS-disk laser structure grown by metal-organic vapor phase epitaxy (MOVPE) on GaAs substrate consists of AlGaAs-Bragg mirror designed for 1000 nm. It is concluded that the scalability of the OPS-disk lasers concept with pump spot diameter produces multi watt output level with brilliant beam quality and high conversion efficiency.
