- 10:55, 6 November 2009 Pcunni1 talk contribs uploaded File:HBCCO Tdep.png (THz TDS is used to map the temperature dependence of the conductivity in the high-temperature superconductor HBCCO, showing an sharp increase in the imaginary component near the critical temperature where Cooper pairing becomes efficient.)
- 09:41, 4 October 2009 Pcunni1 talk contribs uploaded File:Polymer dynamics.png (The THz conductivity dynamics observed in an amorphous polymer film at various delays after photo-excitation shows an evolution from dispersive transport to a bound excitonic response.)
- 18:48, 24 September 2009 Pcunni1 talk contribs uploaded File:THz Polymer vs ZnTe.png (The THz bandwidth available using polymer detector far exceeds that available using the inorganic crystal ZnTe, due to improved phase matching in the polymer.)
- 09:14, 24 September 2009 Pcunni1 talk contribs uploaded File:THz OR.png (THz "optical rectification" occurs by nearly-degenerate difference frequency mixing between the frequency components of an ultra-short pulse in a 2nd order nonlinear optical medium. This process is capable of producing very broadband THz pulses.)
- 09:08, 24 September 2009 Pcunni1 talk contribs uploaded File:THz PDA.png (Schematic diagrams of THz generation from transient photocurrent in a photoconductive dipole antenna, and detection by an THz field-induced transient photocurrent in a photoconductive switch.)
- 08:47, 24 September 2009 Pcunni1 talk contribs uploaded File:FSEOS of THz.png (In free-space electro-optic sampling, the THz waveform and a ultra-short "probe" pulse propagate collinearly through an electro-optic medium. The THz field induces birefringence in the EO medium through the Pockel effect, rotating the polarization of the )
- 18:30, 23 September 2009 Pcunni1 talk contribs uploaded File:THz exp setup.png (Schematic diagram of a typical THz time-domain spectroscopy experimental setup where THz pulses are generated via "optical rectification" and detected via free-space electro-optic sampling.)
