Overview
The PDH steady frequency control box allows for rapid laser frequency locking and fast locking and re-locking; it can operate steadily over a long period of time. Its control bandwidth control is not less than 10 kHz; its modem is not less than 5 MHz; and ADC ' s additional noise is less than 10 mV/√Hz (10 mHz-1Hz). PDH laser steady frequency control box; its internal integration consists of lasers, steady frequency circuits and lock controllers. The control box allows for laser frequency locking, photopower stabilization and RAM control; users are free to choose according to their needs. The PDH lock-in control box internal integration module has a modem module, a loop filter module, etc.; a mass error signal generation; a PID server; a PZT drive integrated; lock control can be provided for a wide range of common stable frequency technologies; e.g. absorption spectrum, saturation absorption spectrum, spectroscopy, modem transfer spectrum, PDH technology, etc. The panel in the lockbox has a touch screen; it can directly set and adjust the parameters of the system; read the system state; it has a knob; it can adjust the frequency of the built-in laser. The back plate has a communications interface using RS422 protocols; external communications are available; two ±12V power interfaces are available; and power is provided for optical detectors or other devices. A full digital laser lock frequency based on the FPGA can achieve rapid laser frequency adjustments, automatic laser frequency locking and re-locking can stabilize laser power, inhibition of RAM generated in phase-modulations can achieve lock frequency, power control, RAM control, etc
