Event Details & Abstracts

Precision measurements enabled by exquisitely stable optical sources had a profound impact on Boulder’s current scientific enterprise. This talk will start with an overview of fundamental noise processes in oscillators, and highlight some of the major differences between electronic and optical sources. I will then discuss what levels of stability can be reached directly from a laser to date, and how to occasionally dip far below the quantum limit for specific applications. 
As a practical application, I will elaborate on the generation of laser-driven, ultra-low noise microwaves, now readily surpassing the best room-temperature microwave sources at a fraction of their size, weight and power.
