Control and Storage of Femtosecond Pulses via Passive Optical Cavities Ultrastable Ultrafast Lasers, Gain-Less Passive Amplifiers, and Ultrasensitive Wide-Bandwidth Laser Spectroscopy

Abstract

We have been very productive during the entire funding period. We have reached all three goals listed in the project title well beyond the initial expectations and have published a number of high profile papers documenting these successes. We have given numerous invited talks on the research supported by AFOSR. We have achieved direct stabilization of a femtosecond-laser-based optical frequency comb by a high-finesse passive optical cavity. We carried out detailed comparison of two distinct stabilization schemes and the result leads to new understanding of the optimum conditions for cavity stabilization as well as on approaches to overcome limitations on the ability to transfer the frequency stability of the cavity to the microwave domain. The stability of the frequency comb is explored in both the optical and the radio frequency domain. With an independent, stable CW laser, we have verified that the line width and stability of the wide-bandwidth optical comb components, respectively, reach below 300 Hz and 5 x 10-14 at 1 s averaging time, both limited by the reference CW laser.
