Special Issue Information
Dear Colleagues,
Random lasing is a physical phenomenon that is responsible for the generation of a special kind of optical radiation with mixed properties of common light and laser. In a random laser system, the last of the three elements that allow the radiation to persist inside the gain medium for the sufficiently long time required for amplification is missing. Scattering, due to disorder of the material, is the mechanism that increases the radiation lifetime, allowing the stimulated emission to prevail.
Besides the basic interest for studying random lasing, such as the statistical issue of the emission behavior, such an optical source has recently been proposed as a useful and very promising tool for developing optical sensors in several fields, such as biological and medical diagnostics research, earth sciences, optical fiber sensing engineering, and industrial quality control as well as for developing new kind of photonic devices.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
