1064 nm, 10 GHz Bandwidth Intensity Modulator (IM-1064-10-PM)

Data Sheet

Product Overview

The Optilab IM-1064-10-PM Intensity Modulator is designed for external modulation of 1064 nm laser; up to 10 GHz or 12.5 Gb/s. It is also applicable for pulse generation for Ytterbium-Doped Fiber Amplifier amplification (YDFA) in satellite links and active mode locked laser applications. It is a bias-stabilized lithium modulator that proves to be extremely stable for long periods of time, and features excellent stability in a biased circuit, operating from 1030 nm to 1090 nm. It has an excellent operating temperature tolerance ranging from -30º C to +75º C. The IM-1064-10-PM uses a Polarization Maintaining (PM) input and output fiber, featuring separate RF and bias ports.
