FREQUENCY MIXING IN THE INFRARED AND FAR-INFRARED USING A METAL-TO-METAL POINT CONTACT DIODE

Abstract
Metal‐to‐metal point contact diodes were used to obtain the 54‐GHz beat notes between two adjacent 10.6‐μ CO2 laser transitions. The speed of the diodes in the far‐infrared is at least 1000 GHz. This was tested with a 337‐μ HCN laser.
