Laser phase noise effects on the dynamics of optomechanical resonators

open access: yes, 2010
We investigate theoretically the influence of laser phase noise on the cooling and heating of a generic cavity optomechanical system. We derive the back-action damping and heating rates and the mechanical frequency shift of the radiation pressure-driven ...

Laser Pulse Heating of Spherical Metal Particles [PDF]

open access: yes, 2011
We consider a general problem of laser pulse heating of spherical metal particles with the sizes ranging from nanometers to millimeters. We employ the exact Mie solutions of the diffraction problem and solve heat-transfer equations to determine the ...
