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
