WebMay 13, 2024 · Optical cooling has been applied in the development of new types of atom interferometers with unprecedented sensitivity as well as enabling the observation of Bose–Einstein condensation (BEC) [ 18 – 20 ]. In the aerospace field, optical forces have also shown their superiority in providing inexhaustible power for interstellar travel. WebJun 21, 2024 · The cooling of solids by optical means only using anti-Stokes emission has a long history of research and achievements. Such cooling methods have many advantages ranging from no moving parts or fluids through to operation in vacuum and may have applications to cryosurgery. However, achieving large optical cryocooling powers has …

Flat optical Window on newtonians with insulation?

WebThe basic idea of cavity optomechanical cooling is that the optical field introduces extra damping for the mechanical mode. Qualitatively, such optical damping is introduced be- cause the optical force induced by the cavity field reacts with a finite delay time, corresponding to the photon lifetime of the cavity. Web1 day ago · Anyways, I have heard about potential optical flats for newtonians to eliminate the diffraction spikes, but the idea was mostly disregarded as it would dramatically slow down the cooling performance of the dob. However, since SCT-s nowadays are considered to be perfect from the get-go, and no thermal currents thanks to insulation, I wonder what ... cfp opco
