Description
This Compact 1550nm Pulsed Fibre Laser (cPFL-1550) from MW Tech was developed for field applications and generates single frequency short nanosecond pulses at 1550 nm. 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 stabilization, control electronics and firmware that continuously monitor and optimize laser operation.
