摘要： PROBLEM TO BE SOLVED: To provide a wavelength scanning type laser light source capable of rapidly changing the wavelength. SOLUTION: An optical circulator 13 is provided in a loop of an optical fiber 11, and the extracted light is incident on a polygon mirror 25. After the light reflected on the polygon mirror 25 is reflected once at a fixing mirror 27, and the light is made incident again on the other face of the polygon mirror 25, the light is incident on a diffraction grating 28. The diffraction grating 28 is formed into a Littrow structure, in which the light is reflected in the same direction as that of the incident light. Thus, the deflection angle becomes 4Δθ, with respect to a rotation angle Δθ of the polygon mirror 25. When the polygon mirror 25 is fast rotated, an oscillation wavelength which still has a narrow line width is scanned rapidly in a broad band. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To expand a wavelength scanning range in a wavelength scanning type laser light source. SOLUTION: This wavelength scanning type laser light source is composed of an optical fiber loop 11 including a gain medium 12, an optical circulator 13, a light beam deflection part, and a diffraction grating 27. A laser is oscillated, and a trigger signal is detected at each scanning cycle.

摘要： PROBLEM TO BE SOLVED: To obtain a wavelength-variable laser light source capable of generating monochromatic light and rapidly scanning its oscillation wavelength.
SOLUTION: A wavelength scanning type laser light source includes a semiconductor laser 11, a MEMS mirror 13, and a diffraction grating 15. The MEMS mirror is rapidly deflected to change an incident angle to the diffraction grating. By appropriately setting a distance between the MEMS mirror 13 and the diffraction grating 15, a change in an external resonator length and a change in a selected wavelength are synchronized. This method can rapidly drive the MEMS mirror 13, and can rapidly scan the wavelength while maintaining a narrow line width.
