Claim 13:
14. A thermal processing system, comprising:
a stage;
a diode laser source emitting a first continuous-wave light energy having a wavelength less than 1.11 μm;
a first optical assembly that directs the first continuous-wave light energy to the stage as a first beam;
a CO2 laser source emitting a second continuous-wave light energy having a wavelength greater than 1.11 μm;
a second optical assembly that directs the second continuous-wave light energy to the stage as a second beam having an area on the stage less than an area of the first beam, the second beam having a first dimension on the stage that is at least about ten times greater than a second dimension of the second beam.
