Proceedings PaperMulti-Gaussian beams: a super-Gaussian alternative
|Format||Member Price||Non-Member Price|
The multi-Gaussian beam shape is proposed as a model for aperture functions and laser beam profiles which have a nearly flat top, but whose sides decrease continuously. Beams and apertures of this type represent a simple, elegant, and intuitive alternative to super-Gaussian beams. The design of lasers that have these beams as its eigenmodes is discussed. Such laser resonators would have increased energy extraction from the laser amplifier.
