Paper Abstract

Laser trapped mirrors may offer an interesting alternative for very large space telescopes. The use of sub-wavelength structures raises many problems concerning electromagnetism, solid state physics and out of equilibrium micro-scale thermodynamics. Optical trapping in low index media and damping in vaccum are among the main technical difficulties that must be addressed. New experimental techniques are explored. Theoretical issues are discussed, relating to Van der Waals cohesion energy and optical forces in the Mie and Rayleigh ranges.
