Abstract
RIN transfer suppression in 2nd order co-propagating pumping schemes is demonstrated. Suppression is achieved by intensity-modulating the seed laser. This technique may enable the use of Raman fiber lasers in co-pumping architectures.
An optical technique is demonstrated for suppressing the RIN transfer from a high power lower order pump to the signal radiation in a co-propagating 2nd order pumping configuration. RIN suppression is accomplished by intensity-modulating the intermediate wavelength seed semiconductor laser diode.
