Abstract |
The interpretation of an important recent experiment by Pfleegor and Mandel according to the causal formulation of the wave-particle dualism is developed. This interpretation is simpler and seems more satisfactory than that provided by the current ideas on the nature of light. |

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

Abstract |
Heterodyne experiments have been performed in the middle infrared region of the electromagnetic spectrum using the CO2laser as a radiation source. Theoretically optimum operation has been achieved at kHz heterodyne frequencies using photoconductive Ge:Cu detectors operated at 4°K, and at kHz and MHz frequencies using Pb1-xSnxSe photovoltaic detectors at 77°K. In accordance with the theory, the minimum detectable power observed is a factor of 2/η greater than the theoretically perfect quantum counter, hvΔf. The coefficient 2/η varies from 5 to 25 for the detectors investigated in this study. A comparison is made between photoconductive and photodiode detectors for heterodyne use in the infrared, and it is concluded that both are useful. Heterodyne detection at 10.6 µm is expected to be useful for communications applications, infrared radar, and heterodyne spectroscopy. It has particular significance because of the high radiation power available from the CO2laser, and because of the 8 to 14 µm atmospheric window. |
