Coherent Fidelity-2 Ultrafast Fibre Oscillator

Delivers short pulsewidths (<55fs) and high average power (>2W) in a rugged, compact package


With the simplicity and reliability of optical fibre, built to Coherent's exacting industrial manufacturing standards and delivering unmatched ultrafast performance, Coherent's newest fiber oscillator, its Fidelity, is the most powerful and dependable femtosecond light source available.

Coherent's revolutionary ultrafast fibre oscillator platform offers a unique combination of high average power and extremely short pulses in a simple to operate, maintenance-free and compact package.



  • Shortest specified pulse length from a commercial fibre laser
  • High average power >2W
  • Built-in automated pre-chirp pulse compressor
  • Compact footprint
  • Air-cooled
  • Maintenance-free
  • Highly Accelerated Stress Screened (H.A.S.S) Manufacturing
  • Simple front panel user interface
  • Software GUI

Delivering over 2W of sub 60fs pulses at 1070nm, the Fidelity fibre oscillator opens up a broad range of scientific and commercial opportunities in applications as diverse as optogenetics, terahertz generation and fundamental material research. Of course, for ultrafast pulses to be most effective in these types of applications, they must maintain their pulse width (maximum peak power) on target. By incorporating a user-adjustable pre-chirp pulse compressor into the laser head, Fidelity delivers the shortest possible pulses to the sample.
