Laser Sensing Laboratory

Our current research interest is focused on the development of new optical-based sensor technologies for industrial and scientific applications, including climate studies, safety and security, medical diagnostics and industrial processes control. These instruments can be used in remote sensing configuration or as point sensors for in-situ chemical analysis.

Important part of our activities is the development of new sensing techniques such as Chirped Laser Dispersion Spectroscopy, CLaDS. In CLaDS spectroscopic information is encoded into frequency (not ammplitude) of RF beatnote and is retrieved through frequency demodulation process, well-known from FM radio. This makes CLaDS well suited for applications where transmittion fluctuations can occur (such as remote open-path sensing).

More about CLaDS here and here.

With our experience in the area of fiber lasers/amplifiers and highly specialized instrumentation (such as Large Diameter Splicer – LDS System from 3SAE) we also conduct research on the development of fused fiber components fabricated by fiber bundle/fiber tapering such as power combiners and mode field adapters for medium and high power fiber amplifiers and lasers.
