Laser power transmission (LPT) has emerged as an innovative technology revolutionizing long-distance wireless power delivery. The efficiency of an LPT system significantly relies on the performance of the laser diode (LD) driver. This paper introduces an innovative single-stage AC-DC LLC converter with power factor correction (PFC) designed for LD drivers, addressing the specific demands of LDs. The proposed system achieves exceptional operational metrics, including high efficiency and minimal harmonic distortion in the input current. Through meticulous design and evaluation, the system demonstrates its capability to meet the intricate demands of LDs while maintaining minimal current ripple, marking a significant advancement in LPT technology. Furthermore, this study underscores the importance of LD driver efficiency by showcasing a single-stage AC-DC LLC with PFC converter that achieves an outstanding efficiency of 95.44% alongside a minimal current total harmonic distortion (THD) of 2.53%. This research represents a pivotal step toward enhancing LD driver efficiency within the domain of LPT, promising extensive applications in wireless power transmission
