LightWire FFS series

Product catalog summary

Overview
The LightWire FFS series by Ekspla are compact fiber seeders designed for femtosecond lasers, specifically for seeding solid-state femtosecond Yb:YAG, Yb:KGW, and Yb:CALGO based CPA systems. These lasers offer femtosecond pulse durations directly from fiber or chirped pulses, with a broad spectral bandwidth up to 15 nm, enabling pulse amplification with compressed durations of less than 200 fs.

Features

Pulse energy greater than 250 nJ at repetition rates below 200 kHz (FFS200CHI).
Compressed or chirped broadband pulses.
Pulses compressible down to less than 200 fs (FFS100CHI) and less than 250 fs (FFS200CHI).
Pulse duration less than 140 fs (FFS200).
PLL option available upon inquiry.
Customizable chirp profile for FFS200CHI to match CPA system compressor design.

Applications

Seeding femtosecond CPA systems.
Ultrafast spectroscopy.
Time-domain terahertz spectroscopy.

Specifications

Central wavelength: 1030 ± 1 nm for FFS100CHI, 1064 nm for FFS200CHI.
Spectral bandwidth: up to 15 nm for FFS100CHI, greater than 20 nm for FFS200CHI.
Pulse duration: up to 30 ps compressible to less than 200 fs for FFS100CHI, greater than 50 ps compressible to less than 250 fs for FFS200CHI, less than 140 fs for FFS200.
Pulse repetition rate: 50 ± 2 MHz oscillator rate, with pulse picker options available.
Output power: varies by model and configuration, with options for pulse picker inclusion.
Polarization: linear with extinction ratios specified per model.
Optical output: various connector and collimator options available.
Operating conditions: 10 – 30 °C, non-condensing humidity.

Performance
Graphs illustrate the typical dependence of average power and pulse energy on repetition rates for different models, as well as typical spectra and autocorrelation functions.

Ordering Information
Models are customizable with options for optical output, fiber length, pulse picker, power version, and mounting type. Specific configurations are available for different models, with limitations on fiber length for certain models.
