MW Tech PFL-1550-LP

MMW Tech 1550nm Pulsed Fiber Laser

Optimized for Materials Processing at 1550 nm.

Description

This 1550nm Pulsed Fiber Laser (PFL-1550) from MW Tech generates single frequency short nanosecond pulses. It is based on a MOPA (Master Oscillator Power Amplifier) architecture that uses proven subsystems and proprietary laser pulse generation, triggering, gating and ASE suppression techniques. The laser incorporates real-time stabilisation, control electronics and firmware that continuously monitor and optimise laser operation.

There is also a customised 1550nm Pulsed Fiber Laser option (PFL-LF-1550) which is designed for very low repetition frequency operation.

Key Features:

  • Center wavelength: 1545 – 1555 nm
  • Average output power > 1 W
  • Output peak power > 5 kW
  • Pulsewidth < 5 ns
  • Repetition rate: Single-shot to 150 kHz
  • Spectral bandwidth (at FWHM) < 10 MHz
  • Diffraction-limited output beam
