Abstract
Mechanical-free, high-power, high-beam quality two-dimensional beam scanning is strongly required for LiDAR systems for autonomous driving. Here, we propose and demonstrate a new, dually-modulated photonic crystal laser, with which we successfully emit a high-quality laser beam with watt-class power in any desired direction.

Abstract
We develop a self-pulsating photonic-crystal surface-emitting laser with a ring-shaped saturable absorber inside the current injection region, and realize self-pulsation with a peak power of 8W, a pulse width of less than 100ps, and a beam divergence angle of 0.5°.
