ULTRA HIGH FREQUENCY MODULATION LASER OPTICAL GENERATOR OF COMPLEX RESONATOR STRUCTURE

摘要

PURPOSE: An ultra high frequency modulation laser optical generator of complex resonator structure is provided to secure technology to generate continuous wave laser by adjusting polarization controller from single laser optical generator. CONSTITUTION: An ultra high frequency modulation laser optical generator is composed of a ring type optical fiber laser resonator(10), a linear optical fiber laser resonator(20), and 50% optical fiber combinator(30) to combine two resonator(10,20). The ring type optical fiber laser resonator(10) is composed of a 10m light amplified fiber(LAF)(11) for optical amplification, a 20m distribution compensation fiber(DSF)(12) for nonlinear polarization effect, an optical direction controller(13), and a polarization controller(14). The linear optical fiber laser resonator(20) is composed of a mirror(23a,23b) having real 100% reflectivity which is arranged at both end, a 20m distribution compensation fiber(DSF), and a polarization controller(21).
