1550 nm Nanosecond Pulsed Laser Module, 10-1000 ns, 100 Hz-1 MHz (NPL-1550-M)

Data Sheet

Product Overview

The Optilab NPL-1550-M is a variable pulsed DFB laser source, a building block ideal for MOPA, LIDAR, OTDR laser systems development and applications. This fully integrated compact module contains a Distributed Feedback (DFB) laser and variable nanosecond pulse generation circuits. The NPL-1550-M provides 20 mW optical peak power in 1550 nm wavelength region, with a programmable pulse width from 10 ns to 1000 ns, and a selectable pulse repetition rate from 100 Hz to 1 MHz. The optical pulse generation can alternatively be controlled via an external electrical trigger. In a compact design, NPL-1550-M is applicable for OEM integration or as a stand alone pulsed laser source.
