Researchers at the Fraunhofer Institute for Applied Optics and Precision Engineering (IOF) say that they have built a thulium fiber laser capable of emitting 1.91 kW - nearly double the typical output ...

A randomized trial found a similar stone-free rate after pulse-modulated Holmium:YAG (Ho:YAG) laser vs thulium fiber laser (TFL) treatment of kidney stones. An investigator reported trial data ...

Researchers at the Fraunhofer Institute for Applied Optics and Precision Engineering IOF have developed powerful thulium fiber laser systems that almost double the previous performance world record.
