Detailed in a paper just published in the journal Optics Express, the experimental setup uses a tellurium-doped fiber laser operating at 1940 nm to pump a thin-disk holmium-doped yttrium lithium ...

Although samarium-doped lasers are not a new idea, with a red-emitting source developed as long ago as 1979, the latest work utilizes a lithium yttrium fluoride (LiYF 4) crystal, which offers better ...

Fu Yuxi from Xi'an Institute of Optics and Precision Mechanics (XIOPM) of the Chinese Academy of Sciences has developed the first room temperature holmium-doped yttrium lithium fluoride (Ho ...
