Low-power N-type Acousto Optic Driver for 532nm Fiber AOM Series
An acousto-optic driver is an RF driver designed to offer support for acousto-optic device products. It is suitable for driving acousto-optic modulators and frequency shifters with a power requirement of less than 3W. The RF signal produced by the driver is utilized to generate ultrasonic waves in the crystal of the acousto-optic device. The modulation, deflection, or tuning of the beam is influenced by the frequency and intensity of the applied RF signal. The driver features efficient heat dissipation, and employing a matched drive enhances temperature stability.
| Supporting Drive | The model (SGXXXX-33-N-ab) employs “X” to denote the frequency shift function, “Y” for the modulation function, and “T” for the modulation function. The “XXX” signifies the operating frequency, where “33” corresponds to the RF output power. “N” indicates the package type. The letter “A” is used with “1” representing a power supply voltage of 24V and “2” for a power supply voltage of 12V. The letter “b” is designated for modulation type, with “D” indicating digital TTL modulation and “A” representing analog modulation. | ||
