Agafonov, A. N., Choporova, Yu. Yu., Kaveev, A. K., Knyazev, B. A., Kropotov, G. I., Pavelyev, V. S., Tukmakov, K. N., and Volodkin, B. O.

Abstract

This paper presents experimental results on the formation of given laser modes from an illuminating Gaussian beam of the terahertz Novosibirsk free electron laser at a wavelength of 141 μm. Binary silicon diffractive optical elements were applied. The experimental results obtained are in good agreement with the results of computer simulation.

5. Tunable wavelength terahertz polarization converter based on quartz waveplates

Author

Abstract

We present the results of calculation and experimental testing of the tunable wavelength terahertz polarization converter represented by a set of plane-parallel birefringent plates with an in-plane birefringence axis. An experimental device has been produced and tested. The calculations show that the effect of interference between the interfaces, including air gaps, may be neglected. The considered device may be used as a simple narrow achromatic waveplate, or a Solc band pass filter for the specified wavelength.
