The newly developed fiber laser achieves an output of nearly 100 W, which is the current limit for core-pumped holmium lasers. Another major achievement is the overcoming of a long-standing technological barrier: the researchers have succeeded in suppressing the negative effect of high holmium concentration, which previously led to reduced efficiency. This result opens up new possibilities for further increasing the power of fiber lasers in the 2.1 \u00b5m wavelength range.<\/p>

\u201cThe efficiency achieved, combined with high power, represents a significant step forward in the development of fiber lasers. It shows that even at high concentrations of active ions, top-tier performance can be achieved\u2014something that was previously considered a fundamental limitation,<\/em>\u201d says B\u00e1ra \u0160vejkarov\u00e1, co-author of the article.<\/p>

This progress paves the way for scaling up power output to the kilowatt range and expands the potential for using these lasers in a wide range of applications\u2014such as advanced industrial technologies or defense systems.<\/p>
