Compact Fiber Seeders for Picosecond Lasers
FEATURES
▶ Pulse energy >50 nJ at repetition rate <1 MHz
▶ Sub-10 ps pulse duration
▶ Close to Fourier-transform limited spectral bandwidth
▶ Integrated fiber pulse picker for flexible repetition rate control (20 kHz – 40 MHz, burst mode available)
APPLICATIONS
▶ Seeding solid state amplifiers
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.
