Beschreibung
Zusammenfassung:	The present invention relates generally to the field of optical devices and particularly to embodiments of a three-stage PPLN optical parametric oscillator/difference-frequency generator configuration. The present invention allows simultaneous generation of three wavelengths in efficient use of the pump signal (36). The structure of the first embodiment of the present invention comprises a first PPLN element (28) having first and second grating regions (20, 22), and a second PPLN element (30) having its own grating period (24). An input coupler (32) is positioned at the input and exit ends of a resonator cavity (26) and the first PPLN element (28) is positioned between the input coupler (32) and the second PPLN element (30).
