Description

LightWire FPS series fiber lasers are dedicated for seeding solid state Nd:YAG amplifiers. Compact, cost efficient FPS series models deliver sub‑10 ps pulses at 1064 nm wavelength with the average output power up to 200 mW and pulse energy up to 50 nJ. They feature narrow close to bandwidth limited spectrum and low pulse amplitude noise. Wavelength tunability ensures that seed pulses are always spectrally overlapped with the amplification spectrum of your amplifier.

1) Due to continuous improvement all specifications are subject to change without notice.
2) Pulse picker is an option for FPS10, FPS100 models. It supports external gating. FPS200 includes internal frequency divider, which enables pulse repetition rate reduction but does not support external gating.
3) FPS200 model is provided with collimator & isolator node with dimensions 138×52×67 mm.
