Abstract

The present invention involves a Taroz Time Domain Spectrum system.In the Tai Hez time domain spectrum system, the femlose laser radiating femtosecond laser is accurate by the first light, and then the biased mirror divides the femtoseclasty laser into pump light and detecting light.Pump Lighting Sutra First Optical Road component generates a Taihez pulse; detecting the line polarization detection of light -like lights such as the first light road component and the pumping light, and the line polarizer detection light and the Taihez pulse pass through the bouquet.Get the beam that is carried by the pulse information of the Tahez.At the same time, two thick electro -optical crystals are used in the detection device to adjust the angle of the crystal shaft between the two electro -optical crystals.The corresponding phase compensation, thereby realizing the linear detection of the strong Hephz pulse and improved the measurement accuracy.

Description

technical field [0001] The invention relates to the field of terahertz technology, in particular to a terahertz time-domain spectroscopy system. Background technique [0002] Terahertz (THz, 1THz=10 12 Hz) frequency band refers to the range of electromagnetic radiation with a frequency from 0.1 THz to 10 THz and a wavelength between microwave and infrared light. Due to its short time scale, terahertz radiation can provide the ability of ultrafast time-resolved spectroscopy. It can be used to penetrate some materials such as organisms, dielectric materials, and gas phase substances. It can be obtained by analyzing the transflective terahertz signal of the sample material. Information about the composition of the material, as well as its physical, chemical, biological state, etc. Also because of the wide frequency band of terahertz wave and the small photon energy, it will not cause damage to the detection material, so terahertz technology can be applied to many fields such ...
