Optimizing Diamond for Application to Laser Threshold Magnetometry

Abstract

This project was overall a great success. While a couple of the planned avenues of study were curtailed by COVID which resulted in the inability to travel to AFRL, two other studies resulted in some unexpected and highly significant results. The PIs discovered that contrary to expectations, a higher concentration of NV centers does not result in a high signal, but in fact lowers the output due to increased losses through quantum tunneling to the more prevalent neighboring centers. They have also produced the first stimulated emission from diamond emitters which, if experimentally optimized, may increase the sensitivity of these devices into the femtoTelsa range - something which will be a real game-changer if it can be exploited in a more applied setting. Overall I would say this grant has been very fruitful and would be supportive of any future grant applications.
