| Abstract: |
| The characteristics of noncollinear phase matching and quasi-phase-matching in the THz-wave parametric oscillator (TPO) are
investigated. The expression of the effective parametric gain length under the condition of noncollinear phase matching configuration
is deduced. The relationship between the poling period of periodically poled LiNbO3 crystal and the generated THz frequency under the condition of quasi-phase-matching configuration is analyzed. Based on the
analyses above we propose a new TPO configuration which ensures the three mixing waves interact collinearly. The effects of
operation temperature on phase matching are analyzed. |
