Optical pulse compression at 1.319$\mu\textrm{m}$ through fiber-grating pair and further compression using soliton effects

광섬유와 회절격자를 이용한 1.319$\mu\textrm{m}$파장 광펄스의 압축과 솔리톤 효과에 의한 재압축

Utilizing self-phase modulation effects of a dispersion-shifted fiber and delay-line characteristics of two gratings, mode-locked 80 ps pulses at 1.319${\mu}{\textrm}{m}$ wavelength from a Nd: YAG laser are compressed down to 2.1 ps. These pulses are further compressed down to 340 fs using higher order soliton effects in a common single mode fiber.
