发明名称 External cavity type tunable laser source
摘要 An external cavity type tunable laser source has a laser diode which cooperates with a reflecting section to constitute an external cavity, and outputs laser light, a laser driving circuit which supplies a laser driving current to the laser diode, a random noise generator which generates a noise current whose current value varies at random, an amplitude control section which controls an amplitude of the noise current output from the random noise generator based on a light intensity of the laser light output from the laser diode, and a current superimposition section which superimposes a noise current whose amplitude is controlled by the amplitude control section on the driving current output from the laser driving circuit.
