We propose a method for the suppression of relative intensity noise (RIN) at the output of a Raman polarizer, a special type of Raman amplifier that transforms an input weak beam of unpolarized light into an highly polarized amplified beam towards its output. We show that the RIN which is induced by polarization-dependent gain is suppressed whenever the Raman polarizer works in the depleted pump regime.
