Abstract: We consider a bulk silicon crystal as a Mid-IR Raman amplifier and study its Raman amplification. A Raman amplifier is established when an intense pump laser pulse and a Raman laser pulse pass through one silicon simultaneously, with good spatial and temporal overlap. Considering the situation of pumping wavelength at 2.94 μm achievable by using an Er:YAG laser and Raman laser wavelength at 3.47 μm with the 521 cm-1 Raman shift, the properties of the output amplified Raman laser are investigated by numerically solving the coupled transfer equations.
