SINGLE FREQUENCY FIBER LASERS

Koheras single-frequency lasers are longitudinally single-mode and offer extremely low phase- and intensity noise levels. Available in the Erbium or Ytterbium wavelength ranges, the all-fiber DFB design ensures robust and reliable operation for thousands of hours.

They are extremely stable and mode-hop free – even under changing environmental conditions. Furthermore, we can deliver shot-noise limited lasers for applications demanding extra low-intensity noise.

Find the right laser for you

Our Koheras single-frequency Erbium and Ytterbium fiber lasers come in three fundamental configurations: OEM fiber lasers, a modular line card system and a desktop fiber laser range. Choose the format that suit you best - they all offer performance that rival or surpass big scientific lasers, but in a compact and industrial package with market leading reliability.

Koheras ACOUSTIK multi channel single-frequency fiber laser

OEM lasers

Choose the Koheras MIKRO lasers, if you need compact and robust industrial fiber lasers designed for OEM integration. Ideal for sensing applications like DAS, vibrometry or wind LIDAR.

Line card systems

The modular Koheras ACOUSTIK system allows you to mix and match BASIK lasers and BOOSTIK amplifier line cards to create the fiber laser you need. Get up to 16 lines in one system.

Desktop systems

Looking for high power or frequency conversion? Or just a desktop format with an easy interface? The ADJUSTIK, BOOSTIK HP and HARMONIK are for you.
