Paper Abstract

This paper presents a high power laser diode method using a large core combined with mode control. The large core allows for high power, while the mode control in an external cavity maintains the beam quality. Analysis shows beam quality can be kept at the ideal diffraction limit for cores as large as 100 microns (transverse dimensions). Such size cores can support hundreds of watts. This means a new class of laser diodes with brightness levels several orders higher than current devices. Such capabilities are unheard of and will have an overwhelming effect on applications.
