Abstract :
Continuous tunable terahertz pulses were generated with a continuous grating-period change from 65 to 90 μm in periodically poled stoichiometric lithium tantalate crystal. Center frequency was tuned from 0.9 to 1.3 THz with as narrow as band-width of 21 GHz at crystal temperature of 130 K.
