W-type Acousto-optic Q-switch Driver
The W-type acousto-optic driver is an RF driver that provides supporting functions for acousto-optic Q switch products with driving power less than 70 w. By changing the input conditions of digital modulation and analog modulation, the frequency and width of the pulse and the amplitude of the beam are controlled. Unique manufacturing and packaging technologies enable efficient heat dissipation, reliable operation and optimal performance.
Characteristics of W-type Acousto-optic Q-switch Driver
- Fast response time
- High temperature stability and reliability
