We report terahertz-wave generation in the wavelength range of 190~210 and 457~507 mum from forward and backward difference frequency generations, respectively, in a 3.2-cm long multi-grating periodically poled lithium niobate (PPLN) crystal.
We investigated three-stage nonlinear frequency conversion in an optical parametric oscillator to generate laser radiation at 589 nm. We successfully demonstrated the sodium-yellow radiation at a threshold of 650 W by using a 1064-nm pump laser.
We demonstrate difference frequency generation of backward THz waves from collinearly phase-matched, periodically poled lithium niobate. Coherent THz waves between 457~507 mum were generated by using kW pump power at a kHz repetition rate.
We report difference frequency generation of THz waves from collinearly phase-matched, periodically poled lithium niobate crystals. Transform-limited THz-wave pulses with a wavelength range between 190~210 mum were generated at a kHz repetition rate.
