1. A method of operating a system comprising:

  • (a) emitting a transform limited laser beam pulse at a specimen;

    (b) varying the shape of the transform limited laser beam pulse;

    (c) detecting a mass spectrum using the varied shape transform limited laser beam pulse;

    (d) automatically emitting multiple additional laser beam pulses of different pre-determined shapes after steps (a)-(c);

    (e) automatically and electronically analyzing the detected mass spectrum and ranking them based on closeness to a target spectrum;

    (f) repeating steps (d)-(e) to statistically improve detected values without inversion procedures; and

    (g) ranking the likelihood that a compound has been detected and identified.
