Abstract
A theoretical design has been made for terahertz-wave parametric oscillator based on the basic principle of optical parametric oscillator. Paper describes theoretical calculation method, based on phase matching conditions by using Lithium Niobate (LiNbO3) non-linear crystal and this should also fulfill energy and the momentum conservation laws. To design the structure of terahertz-wave parametric oscillator, we have drawn the graphs of the relationship between the refractive index and wavelength when the frequency is in the terahertz region, analyzed the non-collinear phase-matching conditions of the terahertz optical parametric oscillator and draw the characteristics curves for LiNbO3. The shape of the crystal and the angle of cutoff crystal, the tuning range, and also designed the optimal shape of the oscillator for efficient coupling output power.
