New Solution Advances Fiber Stub End Pumping

Facebook X LinkedIn Email
Michael D. Wheeler

A new pumping technology for solid-state lasers incorporates fewer optical elements and a simpler assembly at the same time that it promises greater conversion efficiency and better beam quality. Dubbed fiber stub, the technology could be the cornerstone for compact, semiconductor end-pumped solid-state lasers used in ophthalmology and dermatology. In recent years, engineers have worked to refine end-pumping designs because of the disadvantages of side pumping -- namely, lower pump efficiency. While end-pumped lasers appeared to be a better choice in some circumstances, their design posed a...Read full article
