摘要
A simultaneous RGB generating method by QPM ultra-broadband optical parametric generation in periodically poled crystals is provided to enable efficient ultra-broadband optical parametric generation, the second harmonic wave generation and SFG(sum-frequency generation). A beta-BBO (barium borate) crystal generates a weak signal and an idler light according to a suitable direction of a crystal. A monochromator and a PbS detector measure a light intermediation generation band. Band pass filters(F1,F2) transmit only 1.2~2.5 micrometer bands in order to cut pump light.
