Femtosecond Fiber Lasers


  • Pulse duration down to 130 fs
  • Up to 200 mW output power
  • Fiber delivery
  • Compact, rugged design
  • Low maintenance


  • Ultrafast spectroscopy
  • Time-domain terahertz spectroscopy


LightWire EO-FF series femtosecond fiber lasers are compact, robust and simple to use. Models with average power up to 200 mW, pulse energy up to 5 nJ and pulse duration down to 130 fs are available.


LightWire EO-FF50 is a cost effective turn-key femtosecond fiber laser with fiber delivery of the pulses all the way to your sample. Based on a well-established MOPA scheme, LightWire EO-FF50 model laser ensures a reliable hands free operation due to its all-in-fiber construction.


LightWire EO-FF200 is a higher power and shorter pulse version of the sister model from still very compact and cost effective package. It is especially suited for nonlinear microscopy applications.
