Quantum effects in cyclotron resonance using a CW hydrogen-cyanide laser

A submillimeter resonance spectrometer has been developed, which employs a molecular gas laser as a source of radiation. Cyclotron resonance measurements of the quantum effects in the valence bands in germanium were taken with the use of a CW HCN laser. It is shown that the use of CW instead of pulsed lasers helps to avoid resonance line broadening and permits extensive quantitative results suitable for theoretical analysis to be recorded. The purpose of pursuing these methods to acquire detailed data on quantum transitions in semiconductors is to collect the information needed to design and develop a tunable submillimeter maser based on cyclotron resonance transitions.
