SKU: AOMF
The AOMFL Series Fiberoptic Acousto-Optic Modulators deliver uniquely engineered optical intensity modulation and wavelength shifting with exceptional performance, featuring DC–20 MHz modulation response, low insertion loss (~1.2 dB), high extinction ratio (>62 dB), high polarization extinction ratio (>30 dB), low power consumption, and high optical power handling up to 10W — performance unmatched by other vendors. The device generates a fixed-frequency optical grating inside the crystal using a side-mounted piezo actuator driven at its 80 MHz resonance for maximum efficiency; as light passes through, it is diffracted at the Bragg angle, with the first-order beam precisely aligned into the output fiber. An applied electrical control signal adjusts the resonance acoustic amplitude and thereby modulates optical attenuation. The rise and fall times are determined solely by the laser beam diameter — smaller beams provide faster response at the expense of higher optical loss. Operating over a narrow wavelength band and supporting wavelengths from 350 to 2400 nm, the AOMFL is compatible with all fiber types. The design inherently produces a positive frequency shift, with negative-shift options available, and uses fiber collimators aligned to an epoxy-free acousto-optic crystal path for maximum long-term stability and reliability.
Warning: The device needs to be mounted on a heat sink or on a metal frame
