摘要: The coherence length of frequency-doubled light generated in an optical fiber pumped by at λ = 1.064 μm was measured interferometrically. largest bandwidth for second-harmonic generation a to be approximately 3 A. By coupling and 0.532 simultaneously into unprepared fiber, dynamic grating created the fiber. This made it possible frequency double different wavelengths IR region.
