Software program-defined instrument affords laser stabilization


Moku-Professional, a multiple-instrument platform from Liquid Devices, can now lock a laser’s frequency to a reference cavity or atomic transition. Leveraging a FPGA coupled with an analog entrance finish, Moku:Professional is ready to host a number of devices on a single {hardware} platform. The addition of the Laser Lock Field brings the whole variety of devices accessible on Moku:Professional to 11.

With 4 outputs, the Laser Lock Field permits customers to drive a modulation sign and two actuators from a single gadget. It affords a neighborhood oscillator frequency vary of 1 mHz to 600 MHz (1-µHz decision) and output voltage as much as 10 Vpp to drive units with out an exterior amplifier.

The Laser Lock Field supplies a tap-to-lock function to shortly lock to any zero-crossing on a demodulated error sign. It additionally contains two PID controllers that may be individually configured for quick and gradual suggestions. The quick PID controller helps a double integrator for PI2D management. Extra acquire profiles at decrease frequencies allow efficient stabilization, even within the presence of disturbances like variations in temperature.

Clients who’ve already bought the complete suite of devices for Moku:Professional can entry the Laser Lock Field and extra core enhancements by updating their software program to model 2.3.0.
