abstract = "The performance of a diode laser igniter as a restart-capable device has been assessed for single-port, PMMA and gaseous oxygen (GOX) hybrid motors. For this testing a prototype version of the igniter has been designed and implemented as a substitute to a traditional methane/GOX torch ignition system. Atmospheric condition tests have been conducted on an experimental motor setup. Using three PMMA fuel grains, a total of 46 successful motor ignitions and restarts were achieved. These tests were conducted using a single multimode diode laser with an output power of 10.84 W and a nominal pulse length of one second. In addition, a total of 24 successful ignitions and restarts in vacuum were demonstrated with the same prototype igniter on a PMMA/GOX motor in development at the NASA Jet Propulsion Laboratory. The ignition transient is compared against baseline results from a torch ignition system for atmospheric tests and the ignition delay performance is considered across all tests.",
