Auto-Locked Single Mode Lasers

 

We are interested in developing auto-locked single mode lasers for a variety of experiments with cold atoms such as atomic recoil, gravitational acceleration, magnetic interactions and measurements of natural linewidth.

Performance of the autolock controller over ~150 minutes.

The red curve is error signal required to maintain EDCL on resonance; green curve is laser frequency relative to centre of spectral line used for stabilization.

 

 

 

 

 

               

Histogram from this curve shows frequency stability with a standard deviation of 2MHz.
