ULTRAFAST FIBER L ASERS Compact Fiber Seeders for Femtosecond Lasers F E AT U R E S LightWire FFS series fiber lasers are dedicated for seeding solid state femtosecond Yb:YAG, Yb:KGW, Yb:CALGO based CPA systems. Ekspla offers FFS lasers either with femtosecond pulse duration directly from fiber, or with chirped pulses. Compressed or chirped broadband pulses Pulses compressible down to < 200 fs (for FFS100CHI) and < 250 fs (for FFS200CHI) PLL option (please inquire [email protected]) Other wavelengths available on request Seeding femtosecond CPA systems Ultrafast spectroscopy Time-domain terahertz spectroscopy Typical depedence of average power on the repetition rate for FFS200CHI laser Pulse energy > 250 nJ at repetition rate < 200 kHz (for FFS200CHI) Broad up to 15 nm spectral bandwidth enables amplification of pulses with < 200 fs compressed duration. Special feature of FFS200CHI laser is customizable chirp profile to match compressor design of the CPA system. Typical depedence of average power (blue curve) and pulse energy (red curve) on the repetition rate for FFS100CHI-AOM laser

ULTRAFAST FIBER LASERS LightWire FFS SPECIFICATIONS 11 Model CLASS IV LASER PRODUCT 1 Due to continuous improvement all specifications are subject to change without notice. 2) Other wavelengths available on request for FFS100CHI/FFS200CHI. 3) Chirp profile will be optimized by Ekspla to match customer compressor design. 4) Pulse picker is an option for FFS100 and FFS200 models. It supports external gating. FFS200CHI includes internal frequency divider, which enables pulse repetition rate reduction but does not support external gating. 5) FFS200CHI model is provided with collimator & isolator...
