Quadruple grating period ppln optical parametric oscillator difference frequencygenerator with common doubly resonant cavity |
摘要 |
The present invention relates generally to the field of optical devices and particularly to embodiments of a four-stage PPLN optical parametric oscillator/difference-frequency generator configuration. The present invention allows simultaneously and colinear generation of four wavelengths in efficient use of the pump signal. A first embodiment comprises a singly resonant cavity having an internal monolithic non-linear optical medium disposed in the cavity. The cavity is bounded by an input mirror and an output mirror. The monolithic non-linear optical medium is divided into four regions each having its own grating period. A second embodiment of the present invention comprises a monolithic non-linear optical medium divided into four separate regions. The entrance facet and exit facet of the monolithic non-linear optical medium includes a coating which acts as the cavity mirrors. |
