Spectroscopy e Hlahisitsoeng ke Laser (LIBS), e tsejoang hape e le Laser-Induced Plasma Spectroscopy (LIPS), ke mokhoa o potlakileng oa ho lemoha mahlaseli a kotsi.
Ka ho tsepamisa pulse ea laser ka matla a mangata holim'a sepheo sa sampole e lekiloeng, plasma e hlahisoa ke ho hlasimolla ha ablation, ebe ka ho sekaseka mela ea spectral e ikhethang e phatsimang ke phetoho ea boemo ba matla a elektrone ea likaroloana tse ka har'a plasma, mefuta le tlhaiso-leseling ea litaba tsa likarolo tse ka har'a sampole e ka fumanoa.
Ha ho bapisoa le mekhoa e sebelisoang haholo hona joale ea ho lemoha likarolo, joalo ka Inductively Coupled PlasmaOptical Emission Spectrometry (ICP-OES), Inductively coupled Plasmaoptical mass spectrometry (Inductively Coupled PlasmaOptical Emission Spectrometry) Coupled PlasmaMass Spectrometer (ICP-MS), X-ray Fluorescence (XRF), Spark Discharge Optical Emission Spectroscopy, SD-OES) Ka ho tšoanang, LIBS ha e hloke ho lokisoa ha sampole, e ka lemoha likarolo tse ngata ka nako e le 'ngoe, e ka lemoha maemo a tiileng, a metsi le a khase, 'me e ka lekoa hole le inthaneteng.
Ka hona, ho tloha ha theknoloji ea LIBS e qala ho hlaha ka 1963, e hohetse tlhokomelo e kholo ea bafuputsi linaheng tse fapaneng. Bokhoni ba ho lemoha theknoloji ea LIBS bo bontšitsoe ka makhetlo a mangata Libakeng tsa laboratori. Leha ho le joalo, tikolohong ea tšimo kapa boemong ba sebele ba sebaka sa indasteri, theknoloji ea LIBS e hloka ho hlahisa litlhoko tse phahameng.
Mohlala, sistimi ea LIBS tlas'a sethala sa optical sa laboratori ha e na matla maemong a mang ha ho le thata ho etsa sampole kapa ho tsamaisa disampole ka lebaka la lik'hemik'hale tse kotsi, lintho tse ntšang mahlaseli a kotsi kapa mabaka a mang, kapa ha ho le thata ho sebelisa lisebelisoa tse kholo tsa tlhahlobo sebakeng se moqotetsane.
Bakeng sa masimo a itseng a itseng, a kang thuto ea lintho tsa khale tsa masimo, lipatlisiso tsa liminerale, libaka tsa tlhahiso ea indasteri, ho lemoha ka nako ea sebele ho bohlokoa le ho feta, le tlhoko ea lisebelisoa tse nyane tsa tlhahlobo tse nkehang habobebe.
Ka hona, e le ho fihlela litlhoko tsa ts'ebetso ea masimo le tlhahiso ea indasteri inthaneteng le ho khetholla litšobotsi tsa sampole, ho nkeha habonolo ha lisebelisoa, bokhoni ba tikoloho bo khahlanong le mathata le litšobotsi tse ling tse ncha li fetohile litlhoko tse ncha le tse phahameng bakeng sa theknoloji ea LIBS lits'ebetsong tsa indasteri, LIBS e nkehang habobebe e qalile ho ba teng, 'me e' nile ea tšoenngoa haholo ke bafuputsi linaheng tse fapaneng.
