Optical transmission systems of the present invention include at least one optical amplifier in which pump power being provided to an amplifying medium is amplified using a pump amplifier prior to being introduced into the amplifying medium. In various embodiments, a cascaded Raman resonator is used as a pump booster source to provide Raman amplification of the pump power being supplied from one or more pump sources to the signal channel amplifying medium.
