1. A surface emitting laser (SEL), comprising:
- an absorber integrated with a gain region in a monolithic gain structure resulting in the absorber and gain region being operable with similar mode spot sizes;
the absorber having a reduced saturation fluence relative to a saturation fluence of the gain region; and
wherein the SEL emits passively mode-locked laser output while the absorber and gain region are operating with the similar mode spot sizes.

Abstract
A surface emitting laser (SEL) with an integrated absorber. A lower mirror and an output coupler define a laser cavity of the SEL. A monolithic gain structure positioned in the laser cavity includes a gain region and an absorber, wherein a saturation fluence of the absorber is less than a saturation fluence of the gain region.
