Aspects of the present disclosure provide light detection and ranging (LIDAR) systems and methods for using an electro-optical phase-locked loop (EOPLL) and algorithmic frequency locking hybrid driver to lock a beat frequency to the reference frequency. By using the hybrid driver, the present disclosure solves an architectural problem of LIDAR systems related to limited (e.g., narrow and applicable) reference frequency ranges, and provides a flexible and broad reference frequency range coverage. The present disclosure thus allows LIDAR systems to use the hybrid laser driver to effectively change hardware configurations to achieve desired reference frequencies.
