FSC controller

FSC (Fast Servo Controller) provides high bandwidth and low latency PID/PI²D feedback control can be used for linewidth compression and frequency locking of high-precision optical cavities. All circuit parameters can be set through the front panel of the controller, making it easy to use. And there are two parallel feedback loops, one for controlling the laser current (fast feedback loop) and the other for piezoelectric ceramics (slow feedback loop), which can finely control the laser frequency and achieve a higher mode locking range.

advantage:

○ Low latency (<40 ns)

○high bandwidth

○Intuitive control

○Automatically lock the center of the oscilloscope trajectory

○Dual oscilloscope trajectory selection switch

○Two parallel feedback loops

○PID/PI²D-loop forming

○Ramp generator

○High bandwidth external modulation

○Low noise photodiode power supply (± 12 V)

Typical applications:

○laser frequency stabilization

○Narrow line width

○Cavity locking

○Strong noise suppression

○Frequency offset locking
