MODE SYNCHRONOUS OPTICAL FIBER LASER APPARATUS

摘要

PURPOSE:To realize reduction in size, simplification and matching with optical fiber. CONSTITUTION:An optical fiber amplifier 1 shows normal dispersion with an oscillation wavelength to generate an optical pulse having a large BS chirp. This optical pulse is then compressed to the chirpless, pulse in an optical fiber compressor 3 and is then extracted from an output port of an optical coupler 4. Width of optical pulse may be changed by an optical power in a resonator depending on exciting beam power, abnormal dispersion value and length of the optical fiber compressor 3.
