LOS ALAMOS, N.M. -- Laser displays and semiconductor inspection could be the future applications for a fiber-based solid-state laser that emits in the red, orange, green or blue.The discovery was, in large part, an accident. Timothy Gosnell and Ping Xie of the Los Alamos National Laboratory were conducting routine experiments on light amplification. They reproduced a several-year-old French experiment in which a near-infrared laser beam pumped a ZBLAN optical fiber doped with triply-charged ytterbium (Yb3+) and praseodymium (Pr3+) ions. The French experiment lased relatively weakly at red...Read full article
