Abstract
An improved laser pumping system is provided which utilizes optic fibers configured in a fan-in arrangement and an array of light emitting diodes or diode lasers to which the optic fibers are connected for concentrating light energy on a lasing medium. The improvement is an increase of the amount of light energy that can be applied to the laser within a fixed volume.
Claims3
A laser pumping system for applying radiant electromagnetic energy to a lasing medium, said system comprising:
- a plurality of sources of radiant electromagnetic energy;
- and
- an optic tank for concentrating said radiant electromagnetic energy on a lasing medium;
- said optic link having a plurality of individual optic fibers at a proximal end thereof with each optical fiber being operably coupled to respective ones of said sources, and wherein said plurality converges longitudinally and continually to a single fiber at a distant end such that substantially all radiant electromagnetic energy which passes through said individual fibers passes through said single fiber to a predetermined area of said active medium.
