PY - 2012 DA - 2012// TI - Generation of nanosecond terahertz pulses by the optical rectification method T2 - JETP Lett. JO - JETP Lett. SP - 94 EP - 97 VL - 96 IS - 2 KW - optical rectification KW - lithium niobate crystal AB - The possibility of the generation of quasi-cw terahertz radiation by the optical rectification method for broad-band Fourier unlimited nanosecond laser pulses has been experimentally demonstrated. The broadband radiation of a LiF dye-center laser is used as a pump source of a nonlinear optical oscillator. The energy efficiency of terahertz optical frequency conversion in a periodically polarized lithium niobate crystal is 4 × 10−9 at a pump power density of 7 MW/cm2.
