Terahertz generation by optical rectification
WebRecent theoretical calculations predicted an order-of-magnitude increase in the efficiency of terahertz pulse generation by optical rectification in lithium niobate when 500 fs long pump pulses are used, rather than the commonly used ∼ 100 fs pulses. WebTerahertz emission by optical rectification of an intense 1.5-eV, 50-fs pulse in single-crystal iron thin films grown by molecular beam epitaxy indicates the presence of a magnetic non linearity and a nonmagnetic surface nonlinearity.
