Near-optimal intense and powerful terahertz source by optical rectification in lithium niobate crystal
文献摘要:
Using a 400 μJ ytterbium laser combined with a novel pulse compression technique,we demonstrate a state-of-the-art terahertz(THz)source from the tilted-pulse front pumping scheme in lithium niobate at room temper-ature with record efficiency of 1.3%capable of generating 74 mW of average power and 400 kV/cm at focus.Key points of this demonstration include the use of a pump pulse duration of 280 fs in combination with a stair-step echelon mirror and an off-axis ellipsoidal mirror.This source has unmatched characteristics of generating intense and powerful THz pulses at the same time and remains highly scalable as compared to existing Ti:sapphire-based THz sources pumped in the millijoule range.
