Lub twj tso kua mis teeb muab Nd.YAG siv lead ua broadband txuas ntxiv ntawm lub teeb lub zog.Lub cheeb tsam nqus ntawm Nd:YAG yog 0.730μm ~ 0.760μm thiab 0.790μm ~ 0.820μm.Tom qab lub zog spectrum absorbed, lub atom yuav yog los ntawm qis zog mus rau siab zog.
Qib kev hloov pauv, qee qhov kev hloov pauv mus rau lub zog siab atoms yuav hloov mus rau qib qis zog thiab tso tawm tib zaus monochromatic spectrum.
Thaum tus activator tau muab tso rau hauv ob daim iav sib luag (ib qho yog 100% kev cuam tshuam ntawm lwm 50% ntawm daim iav), ib kab noj hniav tuaj yeem tsim ua qhov uas tsis yog-axially propagated monochromatic spectrum tawm ntawm kab noj hniav: Lub monochromatic spectrum propagating nyob rau hauv cov kev taw qhia axial propagates rov qab thiab tawm hauv kab noj hniav.
Thaum cov monochromatic spectrum propagates rov qab mus rau hauv cov khoom siv laser, nws yog hu ua "tus kheej oscillation" hauv kab noj hniav.Thaum lub teeb lub twj tso kua mis muab lub zog siab txaus atoms nyob rau hauv cov khoom siv laser, lub zog siab atoms muaj qhov hloov pauv hloov pauv hloov pauv, txhawb kev hloov pauv emission, thiab txhawb kev hloov pauv ntawm ob theem.
Lub teeb pom kev emission tau tsim los ntawm kev hloov pauv emission tau zoo ib yam thiab theem raws li qhov teeb meem teeb meem.Thaum lub teeb rov ua dua qhov "active teeb meem inversion xeev" ua kom cov tshuaj nyob rau hauv kab noj hniav, qhov kev siv ntawm monochromatic spectrum ntawm tib zaus yog nce los tsim ib lub laser.
