摘要: We experimentally investigate the spectral details of picosecond supercontinuum pumped at 1064 nm and seeded by a weak continuous wave (~20000 times weaker than the pulse peak power) at several power levels in photonic crystal fibers. Seeding at different wavelengths leads to different spectral details, and the effects to the bandwidth of supercontinuum are also distinct. Spectra can be widened when seeded a continuous wave at 1070 nm, and be narrowed for ~100 nm when seeded at 1080 nm. The influence is enhanced with increasing seeded average power.

关键词: supercontinuum seeded by a weak continuous wave, modulation instability, four-wave mixing
