Product Overview

Acousto Optic Modulator; 1030nm (100 MHz)

These acousto optic modulators (AOM) are an ideal for fast amplitude modulation of laser light in a single mode optical fiber with an operating wavelength range of 1000nm to 1090nm. These fiber coupled AOMs are used in fiber laser Q-switching 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 fiber-coupled AOMs are efficient and are designed to be easy to use. With low insertion loss and high input power capability, they are ideal for a wide range of applications. The Bragg cell material is low-loss, and 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 Fiber AOM

The AOM operates at a set frequency, determined by the physical configuration of the Bragg cell; this model operates at 100 MHz.  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. Two different matched RF drivers are available for driving the 1030nm AOM, one designed for analog input signals and another RF driver for TTL input signals.
