Abstract
In nonlinear optical crystalD, each step of wavelength conversion can be performed using another fundamental wave that is output from light output unit, without using the fundamental wave whose output level has been attenuated after going through wavelength conversion for several steps (wavelength conversion in nonlinear optical crystalsA toC). Therefore, the wavelength conversion efficiency improves and the peak power of optical amplifiersandcan be suppressed, which allows the wavelength of lights that are output from optical amplifiersandto be further narrowed.
