Femtosekunden-Faserlaser der LightWire FFS Serie

LightWire FFS

Die Laser der LightWire FFS-Serie eignen sich für das Seeding von Yb:YAG-basierten CPA-Systemen. Die FFS-Laser sind entweder verfügbar mit Pulslänge direkt von der Faser oder mit gechirpten Pulsen. Eine breite spektrale Bandbreite bis zu 12nm erlaubt die Verstärkung von Pulsen bis <300 fs komprimierter Länge. Ein spezielles Merkmal der FFS200CHI-Laser ist das kundenspezifische, an das Kompressordesign des CPA-Systems angepasste Chirp-Profil.

Features

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

Applications

  • Seeding femtosecond CPA systems

Options

  • Collimated free space output available as option for FFS10 and FFS100 models [code: FFS10/100-COL]
  • Integrated fiber pulse picker option (repetition rate 26 kHz – 52 MHz) with TTL synchronisation interface is available for FFS10 and FFS100 models [code: FFS10/100-AOM]

The LightWire FFS series fiber lasers are dedicated to 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. A special feature of FFS200CHI laser is the customisable chirp profile to match the 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 an internal frequency divider which enables pulse repetition rate reduction but does not support external gating.

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

5) Other fiber lengths: 1 m, 2 m, 5 m are available on request.
