ACTIVE OPTICAL CLOCKS

Frequency Standards and Metrology, 2009
This letter presents the principles and techniques of active optical clock, a special laser combining the laser physics of one-atom laser, bad-cavity gas laser, super-cavity stabilized laser and optical atomic clock. As an example, a compact version of active optical clock based on thermal Strontium atomic beam shows a quantum-limited linewidth of 0.51

Research on elastic modes of circular deformable mirror for adaptive optics and active optics corrections.

Optics Express, 2019
In this paper, an elastic mode method of deformable mirror is proposed to decompose arbitrary wave-front errors of adaptive optics system. The elastic modes are derived with an analytical method of linear piezoelectricity based on a bimorph piezoelectric

Active optics in astronomy – modeling of deformable substrates: freeform surfaces for FIREBall and MESSIER

Journal of the Mechanical Behavior of Materials, 2018
Active optics techniques on large telescopes and astronomical instrumentations provide high imaging quality. For ground-based astronomy, the co-addition of adaptive optics again increases angular resolution up to providing diffraction-limited imaging at ...
