Title: Development of a Regenerative Amplifier for the Coherent electron Cooling Proof of Principle Experiment (CeC-PoP) at RHIC

Abstract

The commercial laser from NuPhoton that was used for the Coherent-electron-Cooling Proof of Principle (CeC-PoP) experiment in the past runs could not meet the tight specifications needed to demonstrate coherent electron cooling due to nonlinear effects inherent to fiber lasers operating at high pulse peak powers. To overcome these limitations, the Laser design was modified prior to the start of the 2018 RHIC run by introducing an additional amplifier stage that allows to take over the majority of the amplification process from the fiber amplifiers to keep the peak power in the fibers low and avoid the accumulation of nonlinear effects. This approach allows for a reduction of the output power of the NuPhoton laser to about 5% of the nominal power level avoiding the accumulation of nonlinear effect and leaving 6mW of unstable IR seed power (See Figure 2) for a subsequent amplification stage.
