Experimental demonstration of multi-point laser ignition of rocket engine on a sub- and small-scale rocket engine.

In 30 seconds

Fiber-distributed laser ignition enables precisely timed, multi-point rocket engine ignition using a single high-energy laser source. This system significantly reduces total vehicle weight and cost while enhancing engine reusability. Experimental results validate the damage threshold and performance of the beam delivery network, demonstrating a reliable alternative to traditional ignition methods.
