METHOD OF EXPANDING WAVELENGTH LOCKED OPTICAL OUTPUT RANGE OF LASER DIODE MODULE WITH EXTERNAL RESONATOR AND LASER DIODE MODULE FOR EXECUTING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method of expanding the wavelength-locked optical output range of a laser diode module with an external resonator. SOLUTION: The temperature of a laser diode is controlled, based on the magnitude of optical output.
