ALS IR CW series is a range of high power, high brightness visible near infrared lasers. Single frequency, single mode infrared lasers offer unique performance in terms of low noise and high power, combined with the inherent efficiency and stability of fibre lasers. The fully integrated laser platform offers diffraction limited output powers in excess of 50 W. Based on a single seeder design, this unique modular setup is used to reach advanced experimental conditions in Atom Cooling research. Power scaling to higher powers is possible.

Applications:

  • Metrology
