| We introduce a novel type of light-matter interaction force microscopy and spectroscopy, called as "Photo-induced force microscopy''. We visualize the optical interplay between tip and sample junction at molecular level in ambient condition. The linear and nonlinear optical responses such as localized permittivity, stimulated Raman and pump-probe are addressed at space--time limit. The ability of control the force at nano/molecular scale in ambient condition leads to a variety of potential application such as single molecule study, nano-printing, nano-architecturing with chemical selectivity. |
