Get the ultra-low noise and high power from Koheras lasers and amplifiers
You get a stable, narrow-linewidth fiber laser with intrinsically low phase noise from the Koheras BASIK C15 or E15 pump laser.
If you need an even lower relative intensity noise, order the RIN reduction option.
Have a quick look at the noise specification to see if the BASIK laser would work for you:
|Linewidth||< 0.1 kHz||< 15 kHz|
|Max. phase noise||-90 dB((Rad/√Hz)/m)@10Hz
|Max. phase noise||32 (µrad/√Hz)/m@10Hz
|RIN peak||Appr. 0.7 MHz||Appr. 1 MHz|
|RIN level @ peak/10 MHz||<-100 / <-135 dBc/Hz||<-120 / <-140 dBc/Hz|
The Koheras BOOSTIK fiber amplifier extends the output power of the pump laser. It gives you an output power of 2 W. It is the ideal choice for noise-sensitive applications such as squeezed light because it preserves the ultra-low phase noise and narrow linewidth of the Koheras BASIK seed lasers.
This laser is robust enough for oil rigs yet sophisticated enough for the lab
Our fiber laser design is inherently compact and robust. It is developed for a lifetime of above 10 years in demanding environments where uptime is critical. With failure rates lower than 1%, we proudly deliver the most reliable low-noise lasers on the market. Alignment-free and maintenance-free.
The industrial-grade OEM lasers have a rugged design, a stable performance unaffected by changing environmental conditions, and wide temperature ranges in the field as well as the lab. We deliver lasers to the most advanced laboratories worldwide such as the Non-linear Quantum optics group at the University of Hamburg and DTU Fysik at the Technical University of Denmark.
We have more than 15,000 Koheras lasers deployed in the harshest environments on – and off – the planet. We have lasers on oil rigs, submarines, wind turbines, and even in space. With over 20 years of experience, we know they last. Also in your lab.
