- Abstract:The Wide Field of View Cherenkov Telescope Array (WFCTA),located at the LHAASO site,requires precise calibration to ensure accurate measurements of ultrahigh-energy cosmic rays. In this work,a portable laser calibration system based on a Nd:YAG laser operating at 355 nm is developed to provide well-defined laser energy and emission direction. The system integrates power management,temperature control,damping structures,north and horizontal calibration,and an automatic control program to support stable operation in harsh high-altitude environments. Field experiments demonstrate that the system can achieve reliable pointing accuracy and energy stability,meeting the calibration requirements of WFCTA.
