High-power single-frequency fiber lasers with diffraction-limited spots are indispensable for a wide range of photonic applications and are particularly in advanced detection and sensing technologies.

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 ...

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.
