1. A method of indirectly cooling an optomechanical resonator, comprising impinging a laser on an optomechanical resonator attached to a substrate,
wherein the optomechanical resonator comprises:
a cantilever;
a cooling end of the cantilever, comprising a laser-induced cooling element;
wherein the laser induced cooling element comprises a microcrystal cooling material within the Mie-regime for light scattering; and
an attachment end of the cantilever, attached to a substrate; and
wherein the laser has a peak wavelength in the near-infrared band.
