LabView code for offset locking a master laser to a Fabry-Perot cavity along with active slave locking

Experimental setup for atomic laser spectroscopy and offset frequency locking in high magnetic fields (offset of up to 19 GHz at 1 T).

Laser locking software designed to use a reference HeNe laser and generate an error signal for long term stability control. Original code by Alexia Landry, PID controller and DAC output added here.
