Femtosekunden-Faserlaser der LightWire FFS Serie

LightWire FFS

LightWire FFS series compact Fiber Seeders for Femtosecond Lasers LightWire FFS series fiber lasers are dedicated for seeding solid state femtosecond Yb:YAG based CPA systems. Ekspla offers FFS lasers either with femtosecond pulse duration directly from fiber, or with chirped pulses. Broad up to 12 nm spectral bandwidth enables amplification of pulses with < 300 fs compressed duration. Special feature of FFS200CHI laser is customizable chirp profile to match compressor design of the CPA system.

1)Due to continuous improvement all specifications are subject to change without notice. For latest product information please visit EKSPLA.

2)Chirp profile will be optimized by Ekspla to match customer compressor design.

3)Pulse picker is an option for FFS10, FFS100 models. It supports external gating. FFS200CHI includes internaly frequency divider, which enables pulse repetition rate reduction but does not support external gating.

4)FFS200CHI model is provided with collimator & isolator node with dimensions 104x52x67 mm.
