Matla a marapo a laser a bua ka matla a fetisitsoeng ke ho putlama ha laser ka yuniti. Ka tloaelo, libaesekopo li ka siea maqhubu a tsoelang pele (CW) kapa maqhubu a morao, ka lisebelisoa tse ngata tse kang ho sebetsa lintho tse ngata tse kang ho etsa lintho tse hole le tsa mahlale. Ho utloisisa litšobotsi tsa laser matlafatsong ea laser matla a ho ntlafatsa ts'ebetso ea ona le ho ntlafatsa ts'ebetso ea kopo.
1. Tlhaloso le tekanyo ea matla a Hunse
Mohloli oa laser matla ke matla a lahletsoeng ke pulse e 'ngoe le e' ngoe ea laser, hangata e lekantsoe ho joules (j). Li-laser tsa ho tsoelang pele (CW) tsa lasere
Matla a lolse a ka baloa ho sebelisa foromo e latelang: e = pepek à. Moo e ke matla a matla (joules), phofo ke matla a hloekileng a pulse (watts), metsotsoana). Sena se bolela hore matla matla a amana ka kotloloho le matla a ka bobeli a leholimo le bophara.
2. Lintlha tse amang matla a pulse matla
Lintlha tse 'maloa li susumetsa matla a matla a laser, ho kenyelletsa:
①Moralo oa Laser le mofuta:
Mefuta e fapaneng ea li-Lases e ama boholo ba matla a Hunse. Mohlala, libang tse tiileng tsa mmuso ka thata li fana ka matla a ho putlama, a loketseng likopo tse hlokang tlhahiso e phahameng. Ka lehlakoreng le leng, fibers e ka hlahisa mehaho e phahameng ka ho fetola ho beha sebaka sa tsona.
②Pulse Nako ea nako (pharam):
Lekhulo la makhasi a ho hula, ho phahamisetsa matla a phahamisitsoeng ka nako e fanoeng, e leng se lumellang matla a phahameng a Hulles. Bophara ba ho phatloha ka bophara ba li-laeses ka tloaelo li ka fetoha haholo lipakeng tsa batho ba botona le bo-naneseconds
③Matla a Laser le Ts'ebetso ea Matlafatso:
Phetoho ea laser e lekola tlhahiso ea matla. Litsamaiso tse ling tsa Laser li ka ntlafatsa ts'ebetso ea ho soma ka ho ntlafatsa moralo oa phaello ea phaello kapa laser ka hona, matla a bohloko a thabo.
④Amplifiers:
Tsamaiso e mengata ea laser ea matla a phahameng ea laser, li-amplifers li sebelisoa ho eketsa matla a tlhahiso. Ka ho pheta-pheta mekhahlelo ea mekhahlelo-likarolo, matla a Thanya a ka akhotsoa haholo.
⑤Laser drive ea hajoale:
Tsamaiso ea hona joale ea Diode ea laser ea laser kapa laser ke sesosa sa bohlokoa se susumetsang 'muso oa lona le matla. Ka ho fetola boemo ba hona joale, mmuso oa laser o ka fetoloa, ka hona o ama tlhahiso ea matla.
3. Likopo tsa Matla a Laser
Boholo ba matla a laser a laser a khetha ho ikarabella bakeng sa libaka tse fapaneng. Likopo tse ling tse tloaelehileng li kenyelletsa:
①Ts'ebetso ea boitsebiso:
Ka lalong ea laser, ho itšeha le ho ngola, ho ea matla ho ka laoloa hantle ho fihlela katleho e sebetsang le e hlakileng. Matla a phahameng a Hume a loketse ho sebetsa lisebelisoa tsa tšepe, ha lithaole tsa matla a tlase li sebelisoa bakeng sa kalafo e ntle ea bophahamo.
②Litšireletso tsa Bongaka:
Li-Laser li sebelisoa haholo lefapheng la bongaka, haholo-holo bakeng sa lingaka tsa letsoho, liphekolo tsa letlalo le kalafo. Mohlala, li-Laser tse nang le matla a phahameng li ka tsepamisa matla a maholo libakeng tse nyane ho ea libakeng tse nyane tsa lisele tse bolaeang mafung kapa ho phekola maemo a mahlo a kulang.
③Lindar le ho khothatsa ka tlase:
Theknoloji ea Lidar e itšetleha ka lipalesa tse phahameng tsa matla a matla bakeng sa ho tseba le ho nahana. Ka ho beha leihlo la tikoloho, ho khanna maikutlo le ho betla leihlo, ho utloahala matla a matla a ho aha ka kotloloho sebaka sa ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho lemoha ho aintive.
④Patlisiso ea Saense:
Lijana tse theohileng le tsona li bapala karolo ea bohlokoa ho limpho ka fisiks, k'hemistry le biology. Ka ho laola matla a ho putlama hantle, bo-rasaense ba ka etsa sephiri se etellang pele, se etsahetseng, se qotsitsoeng ho phophofatsa.
4. Mekhoa ea ho eketsa matla a pulse
Mekhoa e tloaelehileng ho eketsa matla a Helse a kenyelletsa:
①Fumana boikarabello bo bohareng:
Ha u khetha phaello e loketseng le ho ntlafatsa moralo oa Laser Cavity, matla a la laser a ka eketsoa.
②The Amplization ea laser a Amerika:
Li-amplifers tse ngata li ka eketsa matla a ho otla a laser ho fihlela litlhoko tsa likopo tse fapaneng.
③Ho eketseha ha bophara ba hona joale kapa bothateng:
Ho lokisa ho khanna koloi ea laser hona joale kapa bophara ba ho ruruha ho ka fella ka matla a maholo a marako.
④Theknoloji ea Kakaretso ea Pulse:
U sebelisa mekhoa ea ho qobella - nako ea pulse e ka khutsufatsoa, e eketsa matla a eona le ho lokolla matla a eketsehileng ka nako e khuts'oane.
5. Q QALANG
Tekanyetso ea laser matla ke paramente ea bohlokoa e amang ts'ebetso le tšebeliso ea lipalesa masimong a fapaneng. Ha ho na le tsoelo-pele e tsoelang pele ea theknoloji ea Laser, laSers e tla ba le lits'ebetso tse pharaletseng indastering e mengata. Ho Tloha Ho Pholotsoa kalafong ea kalafong e haufi le ea ho batloa le kalafo, ho na le lipehelo tse phahameng tsa matla a makhapetla a likhahla a bula menyetla e mecha. Ho utloisisa mehopolo ea mantlha ea matla a ho pullalisa le ho etsa lintho tsa ho susumetsana ho ka thusa ho etsa liqeto tsa mahlahahlaha le ho sebelisa litsamaiso tsa Laser.
