Thulium Fiber Laser 650 W QCW / 150 W CW

High Power 2 µm Thulium Fiber Lasers
  • 650 W peak power in 4 RU housing
  • Emission wavelength at local Absorption maximum of Water
  • Compact Design
  • Water cooled

The new fiber laser module from Futonics is based on a thulium fiber laser oscillator with wavelength stabilization by fiber Bragg grating (FBG). Due to the high peak power, the high beam quality and the compact design, these new products are ideally suited for many medical and technical applications.
