High-energy 1550 nm pulsed fibre amplifier prototype

A polarization-maintaining pulsed amplifier prototype with reported high-energy operating points.

Functional prototype; released availability unconfirmed

  • 1545-1565 nm wavelength range
  • >20 W reported average output
  • Up to 80 µJ reported pulse energy

Define pulse duration, repetition rate and energy as a matched operating point. The published maxima cannot all be combined; the prototype information is retained as a development reference.

Configuration options

Each row is a separate configuration. Limits from different rows must not be combined.

Conditions and configuration notes

  • Pulse energy, peak power, average power and repetition-rate extremes are not one simultaneous operating point.
  • A deep-space optical-communications standard is a design objective, not an established compliance claim in this draft.
  • Hollow-core delivery is described as an investigation and is not assumed to be included.

Applications to discuss

  • Pulsed optical-communications research
  • Photoacoustic research
  • Scientific pulse experiments
