摘要
In an external cavity wavelength tunable laser device including an external cavity (20) which includes a semiconductor optical amplifier (2) and performs laser oscillation operation by feeding back external light, a wavelength tunable mirror (7) having at least a single peak reflection spectrum characteristic within a laser wavelength tuning range is placed on one end of the external cavity (20), and a Fabry Perot mode interval determined by the effective length of the external cavity (20) is not less than 1/10 times and not more than 10 times the reflection band full width half maximum of the wavelength tunable mirror (7).
