Claim 14:
15. A characterization system comprising:
a laser-sustained light source comprising:
a gas containment structure configured to contain a volume of gas, wherein the gas containment structure includes a glass wall, wherein the glass wall includes an OH concentration distribution that varies gradually through the bulk region of the glass wall;
a laser pump source configured to generate an optical pump to sustain a plasma within the gas containment structure;
a light collector element configured to collect at least a portion of broadband light emitted from the plasma, the gas containment structure formed from a glass material at least partially transparent to illumination from the laser pump source and at least a portion of broadband radiation emitted by the plasma;

a set of illumination optics configured to direct broadband light from the laser-sustained light source to one or more samples;
a set of collection optics configured to collect light emanating from the one or more samples; and
a detector assembly.
