Photothermally induced dynamics in partially coated loaded microcantilevers

Cooling of microcantilevers in a Fabry-Perot cavity either by radiation pressure or using the photothermal effect has attracted significant attention lately. We present ongoing experimental results on partially coated microcantilevers which are either loaded ( gold sphere) or have a coating only at the tip. In particular, we will compare the results with that of recent work on fully coated cantilevers.
