Description
Steady-State Microbunching (SSMB) proposes a novel mechanism for generating high-average-power coherent radiation spanning from THz to EUV, with significant potential for various applications. This paper presents the development of a laser system tailored to serve as the modulation laser for the second phase of the SSMB proof-of-principle (PoP) experiments. To verify the stability of microbunching, we have developed a 1064 nm laser system with a burst-mode time structure, achieving peak power exceeding 20 kW. Ensuring the stability of the electron bunches' turn-by-turn phase within the storage ring is crucial for coherent modulation. To address this, we employ an iodine-frequency-stabilized CW seed laser and implement a phase-locking loop. Measurements show that the phase error is below 0.1%π, fulfilling the experimental requirements. The laser system is scheduled for shipment to Berlin, Germany, where it will be integrated with the MLS quasi-synchrotron ring at HZB for the SSMB PoP II experiment.
