Random laser as a potential tool for the determination of the scattering coefficient

The determination of the optical properties of a turbid medium is a major topic in the field of optics. Generally, they comprise the parameters µ _a , µ _s , g and n. There is, however, a lack of techniques for the direct determination of the scattering coefficient µ _s . This study, therefore, proposes the random laser (RL) as a tool to directly measure µ _s - and not ${\mu }_s^{\text{'}}$ . Evidence is found that it is possible to determine µ _s in the diffusive regime by means of the RL. Based on these findings, a local model of the RL is developed and presented in this study.
