In laser sensor and measurement applications the challenges of the design of fast driver circuits is a very demanding task. This white paper describes the design of fast driver circuits, PCB layouts and optical measurement considerations, as well as a solution to achieve an ideal design for pulses as short as 2.5ns.

We report measurements of dynamic (ac) electrical conductivity in borosilicate glasses doped with the semiconductors CdSxSe1-x and AgI in a wide range of frequencies and temperatures. The concentrations of homogenously dissolved dopants are governed by the heat treatment conditions of the glass samples leading to a creation of CdSSe and AgI nanocrystals. The ac conductivity rises with increasing average size of the CdSSe nanocrystals, in contrast to the case of the metal halide doped borosilicate glasses.

Thermal imaging cameras allow researchers to not only see volcanic heat, but also to get non contact temperature readings from a safe distance, which keeps the researchers out of harm’s way.
