Title:
PULSED SEMICONDUCTOR LASER
Document Type and Number:
WIPO Patent Application WO/2013/152447
Kind Code:
A3
Abstract:
In accordance with an aspect of the invention, a laser for emitting pulsed electromagnetic laser radiation is provided, the laser being a vertical external cavity surface-emitting laser and comprising an optical resonator being defined by a radiation direction arrangement comprising two end reflectors, and the optical resonator defining a laser radiation beam path; the laser further comprising: - an essentially plane semiconductor gain structure having a surface plane for emitting said laser radiation; - pump for exciting said semiconductor gain structure to emit the laser radiation from the surface plane; - a mode locker arranged in the beam path for mode locking the laser radiation; - wherein the radiation direction arrangement is configured to direct the laser radiation on its path from one of the end reflectors to the other one of the end reflectors a plurality of times onto the semiconductor gain structure surface plane to stimulate the emission of the laser radiation from the semiconductor gain structure.
