The Fiber-coupled Acousto-optical Modulators(AOM) is made with high quality. The acousto-optic modulator has an acousto-optic medium and a piezoelectric transducer. You can see the two parts in the picture, the modulator and the driver.You need to send us the requirements: Wavelength,Frequencycy,Fiber Type,Fiber Jacket on In&Out, Fiber Length. You will see them at the bottom of this page. Read

It acts as a pulse picker to control the laser output pulses. By dividing down the laser, the laser repetition rate of the output pulses can be adjusted without affecting the pulse energy. The price is for sample fee. Please contact us if you have any questions.

Operation procedure
1. To connect the the 25 pin to the control box and the circuit board, the RF line connect to the driver and the head of Q head .
2.To connect the output of 24V DC voltage of the power supply to the input voltage of the AOM driver. (black for the GND, red for the 24V, do not reverse connection.)
3.To connect the TTL singal in the circuit board to the the signal input terminalof the AOM (black GND to connect the white cable of AOM and red TTL signal to the blue of AOM， do not reverse connection.)
4. Switch on the power supply then adjust the frequency by controlling the control box

Fiber-coupled is also named to fiber pigtailed, the fiber length is customized.1 meter fiber is used in most of the AOM applications.
An acousto-optic modulator (AOM) uses the acousto-optic effect to diffract and shift the frequency of light using sound waves. They are used in lasers for Q-switching, telecommunications for signal modulation, and in spectroscopy for frequency control. See more details
here.AOM is a device which can be used for controlling the power, frequency or spatial direction of a laser beam with an electrical drive signal.
The high frequency pigtailed AOM has a frequency of 200 MHz. High power AOM has an output power as high as 20W.
