Solid state laser with high efficiency and quality in pumped laterally.

摘要

A solid state laser high efficiency semiconductor diode pumped laterally by causing a region of absorption within the active media.The good overlap of this area with the fundamental transverse mode of the laser provides high efficiency laser.A mechanism for spectral narrowing of the pump generates a high absorption within the active media with more similar to an exponential profile when compared with a diode which does not have this di...Spositivo.The narrowing of spectral emission of the diode does with that there is no pumping frequencies outside of the absorption maximum of the crystal.Which are less absorbed and promotes the transport of an important fraction of the energy to regions far from the surface, and more deeper of the crystal.The region of pumping well bounded spatially ensures that even for very high pumping powers of the regions outside the area of overlap accumulate enough energy for permiIRR oscillation order transverse modes, while maintaining the high quality of laser beam to very high powers.The best definition space of the pump ensures a more perfect overlap with the laser beam, even at higher powers.Assessing higher output and a higher efficiency of the device.The technology applies to way especially advantageous means to solid state lasers with moderate absorption, but also showed excellent results in means of high absorption.
