Abstract: This paper reviews the study by Tang et al. on using a Laguerre-Gaussian (LG01) mode laser heater to suppress microbunching instability (MBI) in free-electron lasers (FELs) [1].Their results show that the LG01 mode effectively stabilizes FEL beams by minimizing energy fluctuations that degrade beam quality.In this review, alternative methods for generating donut-shaped intensity profiles with fixed polarization are discussed, along with other potential laser modes that could serve similar applications.Additionally, the impact of laser wavelength on heater performance and technology recommendations are explored.This analysis demonstrates how varying parameters and modes could further optimize FEL beam quality.
