We report experimental studies on Kerr optical frequency generated with a a magnesium fluoride whispering gallery-mode disk-resonator. We particularly focus on microwave generation obtained after extracting the beat-note of the comb through fast photodetection. Primary comb patterns are excited through detuning the laser frequency with regards to the cold-cavity resonance, and they provide microwaves with different frequencies and high spectral purity.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the conference proceedings. They include the speaker's narration along with a video recording of the presentation slides and animations. Many conference presentations also include full-text papers.
