| 1. A method for initiating and sustaining a combustive reaction in a solid fuel, said method comprising:
generating at least one pulsed optical signal;
directing the pulsed optical signal to a plurality of ignition points within a single combustion chamber containing the solid
fuel;
modulating the pulsed optical signal to initially have a first peak power sufficient to initiate a combustive reaction in
the solid fuel; and
modulating the pulsed optical signal to subsequently have a second peak power sufficient to sustain the combustive reaction
once the combustive reaction is initiated.
