1550 nm Variable Pulsed Source Benchtop, 10-250 ns, 4-200 kHz
The Optilab VPS-1550-B-A is a variable pulsed DFB laser source. It is 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 VPS-1550-B-A provides 20 mW optical peak power in 1550 nm wavelength region. The pulse width is programmable from 10 ns to 250 ns and the pulse repetition rate is selectable from 4 kHz to 200 kHz. Pulse generation can alternatively be controlled via an external electrical trigger. In a compact design, VPS-1550-B-A is either for OEM integration or as a stand alone pulsed laser source.
