Frequency Multiplication of Terahertz Radiation in the Crystals of Strontium Titanate Paraelectric

摘要

In this article we have investigated frequency multiplication in the crystals of strontium titanate paraelectric at a temperature of 77 K. Frequency dispersion affects the process of harmonics generation. It has been shown that the efficiency of higher harmonics generation is high and it is equal to 30%. One can perform the selective extraction of certain harmonic by means of an optimal choice of the crystal length.
