Abstract
The present invention advantageously enables single-mode lasing at higher pump power and further enables general reduction of the lasing radiation bandwidth. This is accomplished by producing an appropriate spatial gain distribution inside the laser medium. The present invention further enables advantageous selection of a particular photonic mode for lasing at that mode in a periodic laser by varying spatial gain distribution within the periodic laser medium. Photonic mode selection by varying gain distribution within the laser medium is accomplished in accordance with various embodiments of the present invention.
