Terahertz Generation Through Difference Frequency Mixing of Signal and Idler from an Optical Parametric Amplifier
The thesis investigates the generation of terahertz (THz) radiation through difference-frequency generation (DFG) using chirped and unchirped near-infrared pulses. THz radiation enables the study of phonon dynamics in matter through direct interaction with the crystal lattice. THz radiation is used to induce low-energy excitations in matter while simultaneously avoiding large increases in sample t
