    摘要： In the method for controlling a tunable wavelength laser, information designating an oscillation wavelength is inputted. A driving condition for causing laser oscillation at a first wavelength is acquired from a memory. A control value of wavelength characteristics of the etalon and a difference between the first wavelength and a second wavelength are referred to, and a control value of wavelength characteristics of the etalon for causing laser oscillation at the second wavelength is calculated. The control value of wavelength characteristics of the etalon are assigned to the tunable wavelength laser, and a wavelength is controlled so that a wavelength sensing result becomes a first target value. Information indicating a wavelength shift amount from the designated oscillation wavelength is inputted. The wavelength sensing result is calculated as a second target value. The wavelength is controlled so that the wavelength sensing result becomes the second target value.

    摘要： A method for controlling a wavelength tunable laser is disclosed. The method comprises the steps of: calculating a lasing wavelength from two or more kinds of parameters, the parameters designating the target lasing wavelength; acquiring a driving condition from a memory, the wavelength tunable laser being operable to generate a laser beam of a first wavelength in the driving condition; and calculating another driving condition from the driving condition thus acquired and a wavelength difference between the first wavelength and a second wavelength, the second wavelength corresponding to the lasing wavelength, the wavelength tunable laser being operable to generate a laser beam of the second wavelength in the another driving condition, the wavelength tunable laser being driven in the another driving condition.

    摘要： A lasing wavelength is controlled so that a wavelength detection result becomes a first target value; selection is made to select either a step of calculating a second target value as a wavelength detection result with a shift of the lasing wavelength, or a step of calculating a third control value of a wavelength characteristic of an etalon for letting a laser lase at a wavelength with a shift of the lasing wavelength; in the former step, the lasing wavelength is controlled so that the wavelength detection result becomes the second target value; in the latter step, the lasing wavelength is controlled so that the wavelength detection result becomes the first target value.
