THz generation by optical rectification and competition with other nonlinear processes
We present a study of the terahertz (Tilz) generation by optical rectification in a 2 mm thick <110> ZnTe crystal. The conditions for the most efficient THz generation are described. We investigate the competition between optical rectification (OR), second harmonic generation (SHG), two photon absorption (TPA) and free-carrier absorption in the diffraction limit, for excitation spot sizes small...
متن کاملTHz generation from InN films due to destructive interference between optical rectification and photocurrent surge
We have investigated the characteristics of THz generation including the dependence of the output power and polarization on the incident angle and pump polarization from two series of InN films grown by plasma-assisted molecular beam epitaxy (PAMBE) and metal organic chemical vapor deposition (MOCVD), respectively. Following the analyses of our results, we have attributed the mechanism of the T...

متن کاملHigh Field, High Efficiency Terahertz Pulse Generation by Optical Rectification
The great difficulty of producing high intensity radiation in the terahertz (THz) spectral region by conventional electronics has stimulated interest in development of sources based on photonics. Optical rectification in lithium niobate is an attractive approach, because it supports high generation efficiencies, uses low cost, bulk LN crystals, and is powered by common Yb-doped lasers at wavele...
