An optical amplification apparatus includes a polarizing beam splitter for reflecting a portion of an incident light and transmitting a remaining portion of the incident light, depending upon a polarized state of the incident light, at least two optical amplification means each including a first polarizing plate which makes polarized states of the light before and after the light reflected from the polarizing beam splitter reciprocatingly passes through the first polarizing plate, to be orthogonal to each other, an amplitude division plate for amplitude-dividing the light having passed through the first polarizing plate, into first and second lights, and optical amplifiers for respectively amplifying the first and second lights which are amplitude-divided by the amplitude division plate. The optical amplification means are located such that the light output from upstream optical amplification means is incident upon the polarizing beam splitter included in downstream optical amplification means.
