Abstract
A sample analysis system comprises a laser unit and a spectrometer unit. The laser unit emits a first laser pulse and a second laser pulse towards the sample with a pulse separation time of between about 1 microsecond to 20 microseconds. The laser unit includes an oscillator unit which is configured to generate the first laser pulse and the second laser pulse. A pre-amplifier unit is configured to receive the first laser pulse and the second laser pulse and increase the energy levels of each pulse prior to the pulses being emitted from the laser unit. The spectrometer unit captures emissions generated by the sample after the sample is stuck by the first and second laser pulses and identifies the elemental constituents of the sample using the emissions.
