D2-125 Laser Servo
- Both PZT & Laser Current Feedback
- Double Integrators For Tight Locking
- Peak Lock Option
- Smooth Lockup
- Frequency Jumping and Lockup via Computer Control
- Internal Ramp Generator
- High Bandwidth (10 MHz)
- Reconfigurable PI2D Loop Parameters
The D2-125 laser servo was designed for low-noise servo control of lasers and other experimental systems. The PI2D loop filter, with two-stage integral feedback, provides tight locking to cavities and atomic/molecular transitions. The D2-125 provides full user-control over the loop-filter parameters, enabling servo-loop optimization for a wide variety of plants such as: acousto and electro-optic actuators, voice coils, piezo actuators, etc..
The D2-125 is designed to integrate into our Rackless Rack. As such, it may be powered with our D2-005 or from an adjacent D2 electronics module. If used as a stand-alone product it may be powered either externally (with a D2-005 or from a user supplied power supply via a breakout board) or it may be ordered with an internal power supply and simply plug into a standard AC wall outlet.
