1. A light amplification system, comprising:

  • a fiber-based oscillator, amplifier, and cascaded Raman resonator that are coupled together in series, wherein an oscillator output is provided as an input into the amplifier, wherein an amplifier output is provided as a pumping input into the cascaded Raman resonator, and wherein the cascaded Raman resonator provides as an output radiation at a target wavelength, anda wavelength-dependent loss element, connected between the oscillator and the amplifier, for preventing backward propagation of light from the amplifier and cascaded Raman resonator into the oscillator, whereby the oscillator is operable within a first power level range, and the amplifier and cascaded Raman resonator are operable within a second power level range exceeding the first power level range.
