Operation of an optical in-well-pumped vertical-external-cavity surface-emitting laser

Abstract

We report the operation of an optical in-well-pumped vertical-external- cavity surface-emitting laser. The laser delivers 1 W at 855 nm and is pumped with a cost-effective fiber-coupled laser diode emitting at 806 nm. The laser modal gain is examined and ways of optimizing the system are investigated and discussed. © 2006 Optical Society of America.
