1550nm Pulsed Erbium Fiber Laser

Description

The1550nm Pulsed Erbium Fiber Laser series are especially designed and developed to address LIDAR and remote sensing application. These laser series are "eye safe", and have broad range of pulse widths, repetition frequency, peak power and energy per pulse as well as linear or random polarization operation options.

The Pulsed Erbium Fiber Laser is based on MOPA configuration (Master Oscillator Power Amplifier) that uses laser pulse generation, triggering, gating and ASE suppression technology. This configuration allowed laser pulse characteristics to be easily controlled and adjusted for customized applications. Integrated and highly responsive power monitoring circuitry continuously feeds back to optimize laser operation. This laser module features effective management interface for users to access, monitor and adjust key operating parameters. User-friendly RS-232 interface ensures reliable connectivity with customer's control system.

Features

  • All signal-mode fiber design
  • Adjustable pulse width range 4ns to 50ns
  • Signal/ASE suppression ratio >20dB
  • Random output polarization
  • Highly reliable laser diode pumps
  • Maintenance free operation

Applications

  • LIDAR
  • Mapping
  • Range finding
  • Remote sensing
  • Weather and pollutant
  • Seed source for high power amplifier
