LightWire FFS series

#
Description

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.

Feature

  • Pulse energy > 250 nJ at repetition rate < 200 kHz
  • Compressed or chirped broadband pulses
  • Down to 300 fs pulses available after compression

Related Applications

  • Seeding femtosecond CPA systems

  1. Due to continuous improvement all specifications are subject to change without notice.
  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 internal 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 104×52×67 mm.
