摘要： There has been a problem that pumping light leaks from a part having a coating at the joint of a double-clad fiber added with a rare earth and a general single-mode fiber, and heat is generated partly from the fiber by this energy thus causing deterioration of the fiber. Deterioration of a fiber due to residual excitation light can be prevented by preventing residual excitation light in a double-clad fiber from exiting to a single-mode fiber, and the reliability is enhanced. Output of oscillation light can be increased because output of excitation light is not limited. Furthermore, a laser display having a high color reproducibility can be achieved by employing a light source combining a fiber laser light source and a wavelength conversion module.

摘要： When one tries to obtain high-output wavelength conversion light of class W, the internal temperature of a wavelength conversion element rises significantly to cause an undue variation in phase matching wavelength and thereby it is difficult to match the wavelength of a fundamental wave to the phase matching wavelength. A part of the output of the fundamental wave or pumping light propagating on a fiber is thereby absorbed by doping the fiber with a rare earth element at a set concentration, and the temperature of a fiber grating is raised by heating the fiber grating with heat produced through the absorption. Consequently, the wavelength of the fundamental wave obtained through the fiber grating by widening the grating interval is substantially matched to the phase matching wavelength which can be converted by the wavelength conversion element, and a wavelength converter ensuring a stable high output up to class W is provided.
摘要翻译：当尝试获得等级W的高输出波长转换光时，波长转换元件的内部温度显着上升，导致相位匹配波长的不适当变化，从而难以将基波的波长与相位相匹配匹配波长。因此，在光纤上传播的基波或泵浦光的输出的一部分被吸收，通过用设定浓度的稀土元素掺杂光纤，并且通过用产生的热量加热光纤光栅来提高光纤光栅的温度通过吸收。因此，通过光栅间隔扩大而通过光纤光栅获得的基波的波长基本上与可由波长转换元件转换的相位匹配波长相匹配，并且确保稳定的高输出达到等级W的波长转换器是提供。
