Abstract
A sample of heterogeneous material is analyzed by directing a mixed-wavelength laser pulse at the sample to produce a plasma. The mixed wavelength pulse contains both shorter and longer wavelength components. The composition of the material is determined from the emission spectrum of the plasma.
