摘要: A cA crystal configured to change a frequency of laser through an optical parametric oscillation (OPO) process and difference generation (DFG) is provides. The includes: OPO/DFG segment that quasi-periodically poled yield (i) conversion pump light applied thereto, first signal idler, (ii) second idler signal, by phase-matching OPO therein simultaneously, wherein the has equals sum idler.
