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