The numerical results show that the pulse can get effectively compressed and magnified at the beginning phase after transmitted without the influence of intrapulse cheap womens nike shoes Raman scattering; However, under the influence of intrapulse Raman scattering , pusles form a delay pulse and an ahead pulse, and the ahead pulse will continue to cheap men's nike shoes split into a new delay pulse and a new ahead pulse, and finally form a delay pulse sequence with roughly same direction of nike running shoes transmission, pulse width and amplitude. It is also show that the intrapulse Raman scattering can be weakened to some extent after inputting chirped nike shoespulse. The amplification of ultrashort optical pulses in EDFA is researched. The numerical results show that if the initial distance of near optical pulses is short,the two optical pulses will attract each other and produce a new pulse in the course of nike trainers amplification. As a result, the efficiency of optical pulses amplification will be lower. After enlarging the initial distance, the efficiency of optical pulses amplification will not improve effectively. The transmission of optical pulses introduced initial chirp in EDFA is researched. The results show that after introducing suitable initial chirp, the negative impacts from optical pulses intercation will reduce , the quality of amplification can improve.
