Litaba tsa Laser
Taolo e Nepahetseng ea Mocheso bakeng sa Litsamaiso tsa Laser le Lisebelisoa tsa Indasteri Ho tloha ka 2002
Puo
Leseli la laser le ipabola ka monochromaticity, khanya, tataiso le momahano, e leng se etsang hore e be se loketseng bakeng sa lits'ebetso tse nepahetseng. E hlahisoa ka tlhahiso e tsosolositsoeng le matlafatso ea optical, tlhahiso ea eona e phahameng ea matla e hloka li-chiller tsa metsi tsa indasteri bakeng sa ts'ebetso e tsitsitseng le bophelo bo bolelele.
Theknoloji ea Laser e fetotse liindasteri tse fapaneng, ho tloha ho tsa tlhahiso ho ea ho tsa bophelo bo botle. Empa ke eng e etsang hore leseli la laser le fapane le leseli le tloaelehileng? Sengoliloeng sena se hlahloba likhetho tsa bohlokoa le ts'ebetso ea mantlha ea tlhahiso ea laser.
Phapang Pakeng Tsa Laser le Leseli le Tloaelehileng
1. Monochromaticity: Leseli la laser le na le monochromaticity e babatsehang, ho bolelang hore le na le bolelele bo le bong bo nang le bophara bo fokolang haholo ba spectral. Ka lehlakoreng le leng, leseli le tloaelehileng ke motsoako oa maqhubu a mangata a mangata, e leng se etsang hore ho be le mahlaseli a mangata.
2. Khanya le Matla a Matla: Mabala a laser a na le khanya e phahameng ka mokhoa o ikhethang le matla a matla, a lumellang hore a tsepamise matla a matla sebakeng se senyenyane. Leseli le tloaelehileng, ha le ntse le bonahala, le na le khanya e tlase haholo le mahloriso a matla. Ka lebaka la tlhahiso e phahameng ea matla a lasers, litharollo tse sebetsang hantle tsa ho pholisa, joalo ka li-chiller tsa metsi tsa indasteri, li bohlokoa ho boloka ts'ebetso e tsitsitseng le ho thibela ho futhumala ho feteletseng.
3. Tataiso: Mahlaseli a Laser a ka ata ka mokhoa o ts'oanang haholo, a boloka sekhahla se senyenyane sa divergence. Sena se etsa hore lasers e be e loketseng bakeng sa lits'ebetso tse nepahetseng. Ka lehlakoreng le leng, leseli le tloaelehileng le chaba ka mahlakoreng a mangata, e leng se lebisang ho hasane ho hoholo.
4. Momahano: Leseli la laser le kopane haholo, ho bolelang hore maqhubu a lona a na le maqhubu a tšoanang, mohato le tataiso ea ho ata. Momahano ona o etsa hore lits'ebetso tse kang holography le puisano ea fiber optic. Leseli le tloaelehileng ha le na momahano ona, 'me maqhubu a lona a bontša mekhahlelo le litsela tse sa tloaelehang.
Kamoo Leseli la Laser le hlahisoang kateng
Mokhoa oa ho hlahisa laser o thehiloe holim'a molao-motheo oa tlhahiso e tsosolositsoeng. E kenyelletsa mehato e latelang:
1. Phallo ea Matla: Liathomo kapa limolek'hule ka har'a laser medium (e kang khase, e tiileng, kapa semiconductor) e monya matla a ka ntle, li-electrone tse fetolang ho ea boemong bo phahameng ba matla.
2. Phetoho ea Baahi: Boemo bo finyelloa moo likaroloana tse ngata li leng teng boemong ba thabo ho feta boemong bo tlaase ba matla, ho theha phetoho ea baahi-e leng tlhokahalo ea bohlokoa bakeng sa khato ea laser.
3. Phallo e Tsosolositsoeng: Ha athomo e thabileng e kopana le photon e kenang ea wavelength e itseng, e ntša photon e tšoanang, e hōlisa khanya.
4. Optical Resonance le Amplification: Li-photon tse hlahisitsoeng li bonahatsa ka har'a resonator ea optical (liipone tse peli), li tsoela pele ho holisa ha li-photon tse ngata li ntse li tsosoa.
5. Laser Beam Output: Hang ha matla a fihla moeling oa bohlokoa, lebone la laser le momahaneng, le tataisoang haholo le hlahisoa ka seipone se bonahatsang karolo e itseng, se loketseng ho sebelisoa. Ha li-lasers li sebetsa mochesong o phahameng, ho kopanya mochini o futhumatsang mocheso oa indasteri ho thusa ho laola mocheso, ho netefatsa ts'ebetso e tsitsitseng ea laser le ho lelefatsa bophelo ba lisebelisoa.
Qetellong, leseli la laser le fapane le leseli le tloaelehileng ka lebaka la litšobotsi tsa lona tse ikhethang: monochromaticity, matla a mangata a matla, tataiso e ntle haholo le momahano. Mochini o nepahetseng oa tlhahiso ea laser o nolofalletsa tšebeliso ea ona e atileng libakeng tse tsoetseng pele joalo ka ts'ebetso ea indasteri, opereishene ea bongaka, le puisano ea mahlo. Ho ntlafatsa katleho ea sistimi ea laser le bophelo bo bolelele, ho kenya ts'ebetso ea chiller ea metsi e tšepahalang ke ntlha ea bohlokoa ea ho laola botsitso ba mocheso.
Re mona bakeng sa hau ha o re hloka.
Ka kopo tlatsa foromo ho ikopanya le rona, 'me re tla thabela ho u thusa.

TEYU S&A Chiller e thehiloe ka 2002 e na le boiphihlelo ba lilemo tse 23 tsa tlhahiso ea chiller, 'me joale e amoheloa e le pula-maliboho ea mahlale a pholiso le molekane ea tšepahalang indastering ea laser.
