Ultra-compact 1550nm Pulsed Fibre Laser

This ultra-compact Pulsed Fibre Laser generates single frequency short nanosecond pulses at 1550 nm.


This Ultra-compact 1550nm Pulsed Fibre Laser (ucPFL-1550) from MW Tech was developed for field applications and generates single frequency short nanosecond pulses. It is based on a very compact MOPA (Master Oscillator Power Amplifier architecture that uses proven subsystems and proprietary laser pulse generation. The laser incorporates realtime stabilisation and control electronics to optimise laser operation.
