摘要：
A tuning methods of an External Cavity Laser Diode (ECLD), comprises steps of: (1) providing a laser light to a grating so as to tilt the grating to an optical axis of a collimated laser light, (2) adjusting the orientation of the grating relative to the collimated laser light, (3) monitoring singleness of longitudinal mode and optical power of a light emitted from the grating, (4) calculating an orientation of the grating to exhibit intended optical power at which the singleness of longitudinal mode shows at least predetermined value, (5) adjusting the grating orientation or the optical axis of the collimated laser light to the calculated grating orientation.
