METHOD FOR ADJUSTING ELECTRO-OPTIC MODULATOR IN LASER DEVICE, AND LASER DEVICE |
摘要 |
A laser device includes: a signal light source that outputs seed light; an electro-optic modulator that chops a portion of the seed light outputted from the signal light source and outputs signal light; an optical amplifier that amplifies the signal light outputted from the electro-optic modulator; a wavelength conversion optical element that wavelength converts the signal light amplified by the optical amplifier; a converted light detector that detects the signal light that has been wavelength converted by the wavelength conversion optical element; and an EU control unit that controls the operation of the electro-optic modulator, wherein the EU control unit is adapted, in the state in which the seed light is being outputted, to adjust bias voltage of the electro-optic modulator on the basis of the applied voltage when the intensity of the signal light after wavelength conversion detected by the converted light detector becomes substantially maximum. |
