High 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...

1.7MW Nd:YAG Laser Pulse Generation by A Passive BDN Q-switch

This paper describes the passive Qswitch, based on polymer and organic dye BDN, of a pulsed Nd:YAG laser. Pulses of 27ns duration and peak power of 1.7MW for initial transmission of Q-switch 18.4% 0 T = have been obtained. We have obtained Q-switching efficiency of 77% for train of pulses of 31 and 76.2% 0 T = at the pump energy of 98J. We have also obtained the dependency of laser pulse charac...

Optical field enhancement factor of Silicon and indium phosphide nano-cavities

Nano cavities based on silicon and indium phosphide materials have been comparedin this study, considering field intensity enhancement factor. The results of FDTD based simulations declare that the Si nano-cavity improves confined optical field about 7.7 times higher than the InP based nano-cavity. The introduced dielectric nano-cavities support resonance wavelength at about λ=1.55 μm.

Enhancement of second-harmonic generation from metal nanoparticles by passive elements.

We prepare arrays of gold nanoparticles that include both noncentrosymmetric particles with a second-order nonlinear optical response (active particles) and centrosymmetric particles with no second-order response (passive particles). The plasmon resonances of the active and passive particles are at distinct wavelengths, yet the passive particles modify the electromagnetic modes of the structure...
