New modality in optical microscopy based on laser with injected radiation

Abstract

In this work it is shown, that laser with injection of reflected radiation can possess the high longitudinal spatial selectivity. Laser figures here both the emitter and the detector of radiation. This attribute, having volumetric character for laser fields, can be considered as a new modality in optical microscopy. Using the experimental possibilities we achieved the spatial resolution at a level of several microns. The optimization of laser sources is to lead to longitudinal spatial resolution at a level of nanometers. (© 2012 by Astro Ltd., Published exclusively by WILEY‐VCH Verlag GmbH & Co.
