Repump Laser Light for a Magneto Optical Trap from a Laser Locked to a Frequency-modulated Sideband.

We have worked on rebuilding a magneto optical trap previously used by our lab group. We have set up an additional injection-locked laser for the repump frequency which is locked to a frequency modulated sideband on our trap laser which is generated by phase modulation at 6.66 GHz. This apparatus will be used to study controlling ultracold collisions with frequency-chirped light.
