AOM Acousto-Optic Modulator Coupling System

Center Wavelength: min:1520 nm; typical:1550 nm; max:1580 nm Rise Time: min:45 ns; typical:50 ns; max:60 ns Pulse Off Ratio (Extinction Ratio) [Pulsed]: min:45 dB; typical:50 dB

Acousto-optic modulation loads information onto an optical-frequency carrier through the acousto-optic effect. An amplitude-modulated electrical signal drives an electroacoustic transducer to generate a corresponding ultrasonic field. Light passing through the acousto-optic medium is modulated into an intensity-modulated carrier carrying the information. Shanghai Hanyu’s CoAOM fiber-coupled acousto-optic modulator modules use polarization-maintaining fiber at both input and output, with a high pulse extinction ratio, compact dimensions and an integrated RF driver for convenient system integration.

Operating Wavelength: 355 nm Dielectric Material: Quartz Crystal Transmittance: >99%

JCOPTIX free-space acousto-optic modulators use high-quality piezoelectric transducers such as quartz/lithium niobate and high-purity quartz media for laser control, optoelectronic integration, and research. Inverse piezoelectricity converts RF signals into ultrasound, creating periodic refractive-index changes, a volume grating, in quartz through acousto-optic/photoelastic effects. Adjusting RF intensity/frequency controls diffracted intensity, frequency shift, and direction for efficient real-time electrical-to-optical modulation. Precision structures and SMA-F RF connectors ensure stable transmission: input impedance 50 Ω, VSWR <1.2:1. Lightweight, thermally conductive 6063 aluminum housings and conductive cooling support stable industrial operation and demanding modulation. Free-space AOMs: wavelengths 355 nm, 450 nm, 532 nm, 780 nm, 1064 nm. Apertures: 2.0 mm/3.0 mm/4.0 mm for different beams. Input linear polarization perpendicular to base. Diffraction efficiency >85%. JCOPTIX units combine >85% efficiency and <1.2:1 VSWR for rapid switching/control. Response of 113 ns/mm supports high-speed optical communication; high damage thresholds suit powerful lasers. Applications: laser Q-switching/pulse generation, imaging/display dynamic spot control, fiber signal modulation/demodulation, medical beam-energy control, and diffraction research. RF drivers: frequencies 80 MHz, 100 MHz, 110 MHz. Stable, accurate fixed RF signals. SMA-F output. Quartz oscillators provide stable/accurate fixed signals; different modulation inputs produce required waveforms. Mainly for AOMs, outputs cover 80 MHz, 100 MHz, and 110 MHz. Rise/fall times: <50 ns and <35 ns. Output impedance: 50 Ω. Analog input: 0-5 V. DB9 input and SMA-F interface. Supplied cable has DB9 at one end and bare wires at the other: red +24 V power, black ground, blue digital control, green analog control. Power supplies and modulation generators are not included; contact support for accessory recommendations.
