Lifilimi tsa poleiti ea khalase ea Samarium-dopedhangata li sebelisoa ka har'a likoti tsa laser bakeng sa lits'ebetso tse fapaneng.Lisefe tsena li etselitsoe ho fetisa maqhubu a khanya a khethehileng ha li ntse li thibela ba bang, ho lumella taolo e nepahetseng ea tlhahiso ea laser.Hangata Samarium e khethoa e le thepa ea dopant ka lebaka la thepa ea eona e ntle ea spectroscopic.
Mona ke kakaretso ea kamoo li-filters tse entsoeng ka khalase tsa samarium li sebetsang ka har'a lehare la laser:
Laser Cavity Setup: Lehare la laser ka tloaelo le na le liipone tse peli tse behiloeng ka mahlakoreng a fapaneng, ho etsa resonator ea optical.E 'ngoe ea liipone e fetisetsa karolo e itseng (output coupler), e lumella karolo ea lebone la laser hore le tsoe, ha seipone se seng se bonahatsa haholo.Sesefa sa poleiti ea khalase ea samarium-doped e kenngoa ka har'a laser cavity, ebang ke pakeng tsa liipone kapa e le ntho e ka ntle.
Lintho tse Dopant: Li-ion tsa Samarium (Sm3 +) li kenngoa ka har'a matrix a khalase nakong ea ts'ebetso ea tlhahiso.Li-ion tsa samarium li na le matla a matla a lumellanang le liphetoho tse khethehileng tsa elektronike, tse khethollang bolelele ba maqhubu a leseli boo ba ka kopanang le bona.
Ho monya le ho Etsoa: Ha laser e ntša leseli, e feta ka har'a filthara ea poleiti ea khalase ea samarium.Sefefa se etselitsoe ho monya khanya ka bolelele bo itseng ha se ntse se fetisa leseli libakeng tse ling tse lakatsehang.Li-ion tsa samarium li monya li-photon tsa matla a itseng, li khothalletsa lielektrone ho ea maemong a phahameng a matla.Lielektrone tsena tse thabileng li ntan'o bola li khutlela maemong a tlase a matla, li ntša li-photon ka bolelele bo itseng ba maqhubu.
Phello ea ho Filtering: Ka ho khetha ka hloko motsoako oa dopant le sebopeho sa khalase, sefahla sa khalase sa samarium-doped glass plate se ka etsoa hore se khone ho monya maqhubu a itseng a khanya.Ho monyela hona ho sefa ka mokhoa o atlehileng melapo e sa batleheng ea lesaer kapa tlhahiso e iketsahallang feela ho tsoa ho laser medium, ho netefatsa hore ke feela (ma) maqhubu a laser a lakatsehang a fetisoang ka sefe.
Laser Output Control: Sesefa sa poleiti ea khalase ea samarium-doped se thusa ho laola tlhahiso ea laser ka ho khetha ho fetisa maqhubu a itseng le ho hatella ba bang.Sena se nolofalletsa tlhahiso ea "narrowband" kapa "tunable laser output", ho itšetlehile ka moralo o khethehileng oa filthara.
Ke habohlokoa ho hlokomela hore moralo le masela a li-filters tsa khalase tse entsoeng ka khalase ea samarium li ka fapana ho itšetlehile ka litlhoko tsa tsamaiso ea laser.Litšobotsi tsa spectral tsa filthara, ho kenyeletsoa libanta tsa phetiso le ho monya, li ka hlophisoa hore li tsamaellane le makhabane a hlahisoang ke laser.Baetsi ba sebetsanang le laser optics le likaroloana ba ka fana ka lintlha tse ling le litlhaloso tse ipapisitseng le tlhophiso le lits'ebetso tse ikhethileng tsa laser cavity.
