摘要： A short wavelength light source is provided with a fundamental wave light source for generating a fundamental wave, and a plurality of wavelength conversion elements made of nonlinear optical crystals having periodic polarization-inversion structures and adapted to convert a part of the fundamental wave into a second harmonic, and the nonlinear optical crystals of the plurality of wavelength conversion elements are different in material or composition. By converting the fundamental wave from the fundamental wave light source by the plurality of wavelength conversion elements, the generation of a thermal lens effect caused by light absorption can be suppressed to improve a high output resistance.

摘要： Upon obtaining green light as wavelength converted light by causing infrared light to be incident on a wavelength conversion element, the absorption of the green light occurs due to the generation of ultraviolet light as sum-frequency light of the infrared light and the green light in the wavelength conversion element and the destruction of a crystal composing the wavelength conversion element occurs due to heat generated at this time. In a laser wavelength converter of the present invention, a condensed position of the infrared light in the wavelength conversion element is deviated from a position assumed to be optimal when the influence of the generated heat is ignored. Consequently, crystal destruction is suppressed, a high-efficiency wavelength conversion is enabled and high-output wavelength converted light exceeding several watts, which was difficult to attain in conventional wavelength conversion elements, is attained.

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.
