Provided is a multi-resonant optical fiber laser system including a multi-resonator having an optical fiber containing at least one rare-earth element and an optical fiber inducing the stimulated Raman effect. The multi-resonant optical fiber laser system includes a pump light source irradiating pump light, a first resonator, which includes a first gain medium optical fiber containing at least one rare-earth element and first and second reflectors disposed to face each other across the first gain medium optical fiber and irradiates first laser radiation having a first wavelength by converting the pump light using the first gain medium optical fiber, a second resonator, which includes a second gain medium optical fiber inducing the stimulated Raman effect and third and fourth reflectors disposed to face each other across the second gain medium optical fiber and irradiates second laser radiation having a second wavelength by converting the first laser radiation using the second gain medium optical fiber. The multi-resonant optical fiber laser system furthermore may include a third resonator, which includes a second gain medium optical fiber inducing the stimulated Raman effect and fifth and sixth reflectors disposed to face each other across the second gain medium optical fiber and irradiates third laser radiation having a third wavelength by converting the second laser radiation using the second gain medium optical fiber.
