Coherent Fidelity-2 Ultrafast Fiber Oscillator

Reliability

Coherent rigorously tests every laser during the design and production phases to weed out design and manufacturing weaknesses. This reliability translates into higher data throughout with minimized downtime - lower cost per data point. It delivers a massive reduction in the hidden costs of owning and operating the laser and maximizes experimental productivity.

Broad range of applications

Delivering a high average power of >2W of sub-55 fs pulses at 1070 nm, Fidelity opens up a broad range of scientific and commercial opportunities in applications as diverse as optogenetics, terahertz generation and fundamental material research

Shortest specified pulse length from a commercial fiber laser

By incorporating a user-adjustable pre-chirp pulse compressor into the laser head, Fidelity faithfully delivers the shortest possible pulses to the sample
