1. Excitation apparatus useful in spectrochemical analysis comprising means for holding a sample to be spectrochemically analyzed, MEANS FOR DIRECTING A COHERENT BEAM OF PHOTONS ONTO SAID SAMPLE WITH SUFFICIENT ENERGY TO DISLODGE A PORTION TO BE ANALYZED FROM THE SAMPLE, AND AUXILIARY MEANS FOR RAISING THE EXCITATION ENERGY OF THE DISLODGED PORTION SO PRODUCED TO CAUSE EMISSION, WITHIN A SPECTROSCOPICALLY EXAMINABLE FIELD, OF ELECTROMAGNETIC RADIATIONS CHARACTERISTIC OF CHEMICAL ELEMENTS PRESENT IN SAID DISLODGED PORTION.
