Alkali Lasers Challenge Thin Disks and Fibers

Facebook X LinkedIn Email
Fiber lasers and thin-disk lasers have been the focus of intense development recently because they can efficiently convert the high-divergence output of powerful diode lasers into narrow, high-power beams for countless industrial applications.

Breck Hitz, Senior Technical Editor

What led you to investigate alkalis as laser materials? I’m an inventor, an applied scientist. I like asking what the problem is and then looking for solutions to it. At any given time, we have an arsenal of lasers and we often try to force them to perform applications they’re by no means ideal for. The advent of diode pumps transformed solid-state lasers into a whole new class of device that was able to address elegantly a whole new set of applications. But keep in mind, this happened in 1983 — the concept is 20 years old! I’m proud to have been one of the first people to work on...Read full article
