Design and test of fast laser driver circuits

By iC-Haus
16 March 2012

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

AC conductivity of CdSSe-doped borosilicate glasses

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.
