LBTEK-Your Trusted Partner For Optoelectronic Experiments!

Product Description

Used as an optical switch or variable attenuator
Applicable to laser marking, lithography, material processing, medical surgery, micro-machining
RF drivers and power supplies matched with acousto-optic modulators available

LBTEK acousto-optic modulators operate under the Bragg diffraction condition, producing only the first-order diffracted beam and the transmitted beam. They can be used as optical switches (periodically turning the beam on and off at a set frequency) or as variable attenuators (dynamically controlling the intensity of the transmitted or first-order diffracted beam). Typical applications include laser marking, photolithography, materials processing, medical surgery, and micromachining. LBTEK offers both free-space and fiber-coupled acousto-optic modulators, allowing users to select the configuration best suited to their application. Matching RF drivers are available; by inputting different modulation signals, the driver can generate the required waveform. Custom acousto-optic modulators are also available. For customization requests, technical inquiries, or accessory recommendations, please contact LBTEK Technical Support.

RF Driver

RF signal frequency: 80 MHz, 100 MHz
High stability, high precision
RF signal output port: SMA-F

LBTEK RF Drivers provide highly stable and precise RF signals. By applying different modulation signals, the driver can generate specific waveforms to meet the requirements of optical devices in various applications. These RF drivers are primarily designed for driving acousto-optic modulators. LBTEK offers models operating at 80 MHz and 100 MHz. The input interface is DB9, with an SMA-F output.

Each driver comes with a complimentary cable, featuring a DB9 connector on one end and bare wires on the other, allowing easy connection to the user’s power supply and signal generator. Wire mapping: red = +24 V power, black = ground, blue = digital control, green = analog control. For any technical inquiries, please contact LBTEK Technical Support.

Note: LBTEK RF drivers do not include power supplies or modulation signal generators. For accessory recommendations, please consult LBTEK Technical Support.

Acousto-optic modulator, free-space type, water-cooled

Operating Wavelength: 1040 nm-1080 nm
Incident Light Polarization: Linear polarization, perpendicular to the base
Diffraction Efficiency: ≥80%
High Damage Threshold
Water Cooling Interface Size: Ø6 mm

LBTEK acousto-optic modulators can be used as optical switches (periodically turning the light on and off at a set frequency) or as variable attenuators (dynamically controlling the intensity of transmitted light or first-order diffracted light). To achieve optimal diffraction efficiency, the device requires relatively high drive power. Since conductive cooling is insufficient under these conditions, the modulators adopt a water-cooling design and must be operated with a chiller.

LBTEK offers acousto-optic modulators with an operating wavelength range of 1040 nm–1080 nm, and provides optional supporting accessories including RF drivers, chillers, and power supplies.
