A significant enhancement of the terahertz generation efficiency via two-color laser-induced air ionization, up to 10-3, is observed with increasing pump wavelength. Terahertz peak fields up to 4.4 MV/cm were obtained using 400 μJ pulse energy.

We demonstrate entangled photon triplets from cascaded downconversion. First, we establish the presence of tripartite energy-time entanglement using a new entanglement criterion. Then we show a new source of three photon polarization GHZ states, verifying its quality with an entanglement witness.

The effect of index antiguiding on GaN-based blue and violet laser diodes has been investigated. Strong antiguiding effects are proposed to be responsible for the large dependence of the threshold current density on the ridge etch depth.
