Method For The Efficient Generation Of High Order Hermite Gaussian (HG) Modes In A Laser Cavity

This technology is a method to generate higher order transverse laser modes. This method uses a combination of optical and/or electrical pumps and a VECSEL chip (vertical external cavity surface emitting lasers). Background: There are broad range of applications for higher-order lasers. However, due to low output power and/or large device size the...

Novel Electrically Pumped VECSEL

This invention is a high-power, tunable, electrically pumped VECSEL. By use of a novel pumping geometry, the electrically pumped VECSEL is able to attain high output powers with greater efficiency. Background: A vertical-external-cavity surface-emitting-laser (VECSEL) is a small semiconductor laser not dissimilar to the vertical-cavity surface-emitting...
