Coherent Raman Spectroscopy in Terahertz Region by Using Frequency Chirped Optical Pulses

Abstract

The principle of coherent Raman spectroscopy in terahertz (THz) frequency region using frequencychirped optical pulses is explained. The examples of THz Raman spectroscopy for solid state (β -GaSe crystal) and liquid state materials (CCl4, DMSO/water mixture, aqueous solution of ZnBr2) are demonstrated. The advantage of this technique over the conventional one is the simplicity of the system.
