Abstract:
An ignition apparatus comprising:(a) an excitation light source; (b) a beam splitter positioned to receive output from said excitation light source; (c) a first end of a first optical fiber positioned to collect a first portion of a beam from said beam splitter; (d) a second end of said first optical fiber positioned to deliver said first portion of said beam into a beam combiner; (e) a first end of a second, longer optical fiber positioned to collect a second portion of a beam from said beam splitter; (f) a second end of said second optical fiber positioned to deliver a second portion of said beam from said beam splitter into said beam combiner; (g) an optical fiber connecting said beam combiner to an ignitor laser so as to transport combined beam output from said beam combiner to said ignitor laser; and (h) a lens to direct output from said ignitor laser into a combustible fuel.
