ESPECIALLY WIDEBAND LIGHT SOURCE FOR USE IN SHORT-COHERENCE INTERFERENCE METHOD

摘要

PROBLEM TO BE SOLVED: To provide especially a mechanism for generating a wideband spectrum that can be used as a light source for a short-coherence interference method. SOLUTION: The mechanism has a laser, especially a laser diode for generating a short optical pulse having a wavelengthλp; a highly nonlinear optical fiber in a fine structure, having zero dispersion and abnormal dispersion in group velocity near the wavelengthλp; and a means of introducing the optical pulse into the optical fiber in the fine structure.
