The new Koheras HARMONIK fiber laser system gives you up to 7 W output at 775-780 nm with a unique combination of low noise, sub-kHz linewidth, and excellent beam quality. It’s alignment-free with ...

Cladding light stripper (CLS) technology addresses a major challenge in scaling thulium fiber lasers beyond their long-standing 1 kW power limit. A new self-adapting CLS design distributes heat along ...

Engineers know that measuring dc or low-frequency electrical power is fairly straightforward, but such measurements become more difficult as you go up the spectrum into the tens-of-gigahertz range.

The figure shows the Brillouin-gain-spectrum map obtained along a 13-m single-mode silica fiber. The upper diagram marks a ~1.1-m strained section. The lower color plot displays the corresponding ...
