This report presents additional data on the properties of glass used in lasers as well as operating characteristics of glass lasers. The effect of intense ultraviolet radiation is shown to decrease the output of glass lasers much more than can be accounted for the decrease in fluorescence intensity or absorption of pump light. Comprehensive threshold and output data are given for several lasers...

thin films of binary bi 0 -teo and bi 0 -v 0 systems were prepared by the thermal co-evaporation technique in a vacuum at room temperature. the optical absorption edge of these systems are studied in the wavelength of 200-800 nm using a perkin-elmer uv/vis spectrophotometer. it is found that the value of n=3/2 in the davis-mott equation is best fitted for the fundamental absorption edge for the...

Microsensor wireless networks and implanted biomedical devices have emerged as exciting new application domains. These applications are highly energy constrained and require flexible, integrated, energy-efficient ADC modules that can ideally operate at the same supply voltage as digital circuits. In many applications, the performance requirements are quite modest (100s kS/s). This paper present...
