Construction of MIM Diodes Suitable for Use in FIR Generation By Mixing Two Carbon Dioxide Laser Beams

Abstract

Metal Insulator Metal (MIM) diodes have been constructed with a tungsten whisker making contact with different post materials such as nickle, brass, carbon, stainless steel, aluminum and tungsten. The 1-V characteristics of these diodes have been studied. It was found that 2 mm section cut from a shaving blade held against a polished carbon post showed similar I-V characteristics to the previous diodes. Resistances of these diodes were found to vary between 0.1-1k The use of MIM diodes for CO2 laser mixing is briefly discussed.
