1650nm Fiber acousto-optic modulator (AOM) Overview

These high-speed fiber-coupled acousto-optic modulators (AOM) are an ideal for fast amplitude modulation of laser light in a single mode optical fiber operating wavelength range of 1580nm to 1720nm. These AOMs are used in Q-switched fiber laser and pulse picking applications, narrow line width laser measurements, and many other applications related to precision fiber-coupled systems operating in the nanosecond range.

Low Insertion Loss, High Input Power

These AOMs are efficient and are designed to be easy to use. WIth low insertion loss, high input power capability, and high extinction ratio, they are ideal for a wide range of applications. The low-loss Bragg cell material is chosen for its ability to support the high-Q acoustic refractive index grating that is fundamental to the operation of the AOM.

Matched RF Driver for Acousto-Optic Modulator

The AOM operates at a set frequency of 200 MHz, determined by the physical configuration of the Bragg cell.

In order to drive the AOM, a high power RF signal is needed at the AOM operating frequency; the signal power is typically up to a few watts. An RF Driver/Amplifier is required to amplify the low-level output from a signal generator to the power level needed to drive the acousto-optic modulator. The RF generators offered here integrate seamlessly with the AOMs and provide a one-stop solution for high-speed Q-switched, fiber-coupled laser modulation.

Three different matched RF drivers are available for driving the 1650nm AOM, one designed for analog input signals and another RF driver for TTL input signals. Another model operates with combined analog and digital input signals.
