[PDF] Top 20 An all solid state optical parametric oscillator for the infrared

... In an OPO, waves are generated at two frequencies and so there are the losses of two separate cavities, signal and idler, to be considered. As discussed in chapter 2, a lower threshold can be obtained for an OPO if both ... See full document

... In the unstable resonator, the light rays keep on moving away from the resonator axis until eventually they miss the small convex mirror altogether. The output beam from this resonator will have a doughnut-like shape ... See full document

... A second process uses a fluke of nature in that two strong gain lines in Nd:YAG, the 1064nm and 1319nm lines, are nearly perfect for sum frequency generation to produce 589nm emission [13]. This forms the basis of an ... See full document
