LBTEK acousto-optic modulators can be used as optical switches (to cyclically switch light on and off at a set frequency) or as variable attenuators (to dynamically control the intensity of transmitted light or first-order diffracted light). LBTEK offers acousto-optic modulators with various operating wavelengths from 355 to 852 nm, and provides compatible RF drivers and power supplies for purchase. The RF driver has a fixed frequency output; if broadband tunable output is required, a custom broadband RF driver must be ordered separately.
Note: This product generates heat during operation and should be installed on a thermally conductive mounting base or equipped with a heat sink.

LBTEK acousto-optic modulators can be used as optical switches (cyclically switching light on and off at a set frequency) or variable attenuators (dynamically controlling the intensity of transmitted light or first-order diffracted light). To achieve optimal diffraction efficiency, the driving power is relatively high, and heat dissipation through conduction is insufficient to meet usage requirements. Therefore, the product adopts a water-cooling heat dissipation mode and requires a water chiller for operation. LBTEK offers acousto-optic modulators with wavelengths ranging from 1000 nm to 1100 nm, along with supporting RF drivers, water chillers, and power supplies available for purchase. The RF driver provides a fixed frequency output. If broadband tunable output is required, a customized broadband RF driver needs to be ordered separately.

LBTEK acousto-optic modulators can be used as optical switches (cyclically switching light on and off at a set frequency) or variable attenuators (dynamically controlling the intensity of transmitted light or 1st-order diffracted light). The fiber length of LBTEK fiber acousto-optic modulators is >0.8 m, with FC/APC interfaces for convenient customer connection. LBTEK offers fiber acousto-optic modulators at wavelengths of 780 nm, 1064 nm, 1310 nm, and 1550 nm, and provides optional RF drivers. The RF driver has a fixed frequency output; for broadband tunable output, a custom broadband RF driver must be ordered separately.

LBTEK's acousto-optic modulator series products are based on the principle of acousto-optic interaction, enabling frequency shifting and amplitude modulation of laser light. They can be used as optical switches (cyclically switching light at a set frequency) or variable attenuators (dynamically controlling the intensity of transmitted or first-order diffracted light). They feature fast response time, low insertion loss, high extinction ratio, good temperature stability, and high reliability. The products adopt an integrated structural design with high integration and good stability. The standard wavelength is 1550 nm, the fiber optic interface is FC/APC, and the pigtail length is >1 m. Furthermore, we offer flexible customization services. We can customize the operating wavelength, operating frequency, fiber type, pigtail length, and RF driver according to requirements to meet personalized needs for different application scenarios.

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.
