Claim 4:
5. The combustion burner assembly of claim 1, wherein a portion of the laser tube is disposed within the fuel transport tube, wherein the portion of the laser tube disposed in the fuel transport tube is separated from the ignition tube by a predetermined spacing, wherein the predetermined spacing between the portion of the laser tube disposed in the fuel transport tube and the ignition tube forms the recirculation zone where particles of the fuel carried in the fuel transport tube recirculate for more exposure to the beam of laser light prior to entering the ignition tube, wherein the particles of the fuel in the recirculation zone absorb photons of the beam of laser light, and heat up to cause an initial ignition of some of the particles, the initial ignition causing subsequent absorbing, heating, and ignition of other particles of fuel in the recirculation zone.
