Abstract:
PROBLEM TO BE SOLVED: To provide a laser device capable of changing a laser wavelength over a wide range. SOLUTION: Light beams are emitted from a laser diode 11 having characteristics oscillating a multi-mode and changing the wavelength of an oscillation in response to a temperature, and light beams are reflected from a grating 13. The wavelength of light beams from the laser diode 11 is used as a specified wavelength in response to the positional relationship of the laser diode 11 and the grating 13. The variable range of the wavelength of light beams from the laser diode 11 is extended by cooling or heating the laser diode 11 by a Peltier element 35, and the range of the wavelength is extended in light beams 25 used for electronic equipment.

Abstract:
An evaluation method, an evaluation apparatus, and an exposure apparatus are provided to evaluate the optical property of an optical system to be evaluated by calculating the optical property of a projection optical system using determined pupil barycentric coordinates. A method for evaluating the optical property of an optical system using an interferometer comprises following steps. A first interference pattern is obtained by a interferometer when the arrangement of the moving element of the interferometer in the optical axis of an optical system(4) is the first arrangement. When the arrangement of the moving element is the second arrangement, a second interference pattern formed owing to the interferometer is obtained. The pupil barycentric coordinates of the optical system is determined based on the obtained first interference pattern and the obtained second interference pattern. By using the determined pupil barycentric coordinates, the optical property of the optical system is calculated.
