Optical fiber and the microscopic interactions of light with matter

Microscopic laser light interaction with matter has many consequences. That result depends on many factors: the medium, the matter involved, the light intensity, the wavelength, and the many ways of light, among others. In this contribution, we are going to discuss several results observed when light interacts with matter under different conditions. The observation did use a standard optical fiber and near-infrared radiation. We are going to discuss the basic linear and angular momentum transference, optical trapping; light energy conversions, such as absorption, heating, photochemical reactions, and micro-thermocavitation.
