This study explores the operational dynamics of free-electron lasers (FELs) within the frameworks of the Compton and Raman regimes, and in plasma resonance. The analysis accentuates the interaction of a spherical whistler of Gaussian intensity profile with the FEL under a rippled density plasma, and changes in growth rate and energy exchange efficiency is investigated on various parameters. The paper indicates a substantial increase in growth rate under low guide magnetic fields and precise control on FEL tunability. Our findings offer insights into optimizing FEL operations through strategic parameter adjustments, promising significant advancements in laser technology.
