Ntlafatso ealaser ea fibersebopeho

1, sebopeho sa pompo ea khanya ea sebaka

Li-laser tsa pele tsa fiber li ne li sebelisa tlhahiso ea pompo ea optical,lasertlhahiso, matla a eona a tlhahiso a tlaase, e le ho ntlafatsa ka potlako matla a tlhahiso ea fiber lasers ka nako e khutšoanyane ho na le bothata bo boholo. Ka 1999, matla a hlahisoang ke lipatlisiso tsa fiber laser le tšimo ea nts'etsopele e ile ea robeha li-watts tse 10,000 ka lekhetlo la pele, sebopeho sa fiber laser haholo-holo tšebeliso ea pompo ea optical bidirectional pumping, ho etsa resonator, ka lipatlisiso tsa katleho ea letsoapo la fiber. laser e fihlile ho 58.3%.
Leha ho le joalo, le hoja ho sebelisoa ha fiber pompo leseli le laser coupling thekenoloji ho ntshetsa pele faeba lasers ka ka katleho ntlafatsa dipholo tsa matla a faeba lasers, empa ka nako e tšoanang ho na le ho rarahana, e leng ha e loketseng ho lense optical ho haha ​​tsela ea optical, hang ha laser e hloka ho sisinyeha molemong oa ho aha tsela ea optical, joale tsela ea optical e boetse e hloka ho lokisoa hape, e fokotsang ts'ebeliso e pharaletseng ea pompo ea optical sebopeho sa fiber lasers.

2, sebopeho sa oscillator se tobileng le sebopeho sa MOPA

Ka nts'etsopele ea li-laser tsa fiber, li-stripper tsa matla a cladding li nkile sebaka sa likarolo tsa lense butle-butle, li nolofatsa mehato ea nts'etsopele ea li-laser tsa fiber le ho ntlafatsa ka mokhoa o sa tobang ts'ebetso ea tlhokomelo ea fiber lasers. Mokhoa ona oa nts'etsopele o tšoantšetsa ts'ebetso ea butle-butle ea fiber lasers. Sebopeho sa oscillator se otlolohileng le sebopeho sa MOPA ke likarolo tse peli tse atileng haholo tsa lasers tsa fiber 'marakeng. Sebopeho sa oscillator ka ho toba ke hore grating e khetha bolelele ba nako nakong ea ho oscillation, ebe e hlahisa wavelength e khethiloeng, ha MOPA e sebelisa leqhubu le khethiloeng ke grating e le leseli la peo, 'me leseli la peo lea holisoa tlas'a ketso ea pele. -level amplifier, kahoo matla a tlhahiso ea fiber laser le ona a tla ntlafatsoa ho isa tekanyong e itseng. Ka nako e telele, li-laser tsa fiber tse nang le sebopeho sa MPOA li 'nile tsa sebelisoa e le mohaho o ratoang oa li-laser tsa fiber tse matla. Leha ho le joalo, liphuputso tse latelang li fumane hore tlhahiso ea matla a phahameng mohahong ona e bonolo ho lebisa ho se tsitseng ha kabo ea sebaka ka har'a fiber laser, 'me khanya ea laser e hlahisoang e tla ameha ho isa tekanyong e itseng, eo hape e nang le tšusumetso e tobileng. ka phello ea tlhahiso ea matla a phahameng.

Ka nts'etsopele ea theknoloji ea ho pompa

Bophahamo ba ho pompa ba laser ea pele ea ytterbium-doped fiber hangata ke 915nm kapa 975nm, empa maqhubu ana a mabeli a pumping ke tlhoro ea ho monya ea ytterbium ion, ka hona e bitsoa ho pompa ka kotloloho, ho pompa ka kotloloho ha ho so sebelisoe haholo ka lebaka la tahlehelo ea bongata. Theknoloji ea ho pompa ka har'a sehlopha ke katoloso ea thekenoloji ea ho pompa ka ho toba, moo bolelele ba maqhubu pakeng tsa leqhubu la ho pompa le leqhubu le fetisang le tšoana, 'me tekanyo ea tahlehelo ea quantum ea ho pompa ka har'a sehlopha e nyenyane ho feta ea ho pompa ka ho toba.

Matla a phahameng a fiber laserbothata ba ntlafatso ea theknoloji

Leha li-laser tsa fiber li na le boleng bo phahameng ba ts'ebeliso liindastering tsa sesole, tsa bongaka le tse ling, China e khothalelitse ts'ebeliso e pharaletseng ea li-laser tsa fiber ka lilemo tse ka bang 30 tsa lipatlisiso le nts'etsopele ea theknoloji, empa haeba u batla ho etsa li-laser tsa fiber li ka hlahisa matla a phahameng, ho ntse ho na le mathata a mangata a theknoloji e teng. Ka mohlala, hore na matla a hlahisoang ke laser fiber a ka fihla mokhoeng o le mong oa fiber 36.6KW; Tšusumetso ea matla a ho pompa matla a tlhahiso ea fiber laser; Tšusumetso ea phello ea lense ea mocheso ho matla a tlhahiso ea fiber laser.

Ho feta moo, lipatlisiso tsa theknoloji e phahameng ea tlhahiso ea matla ea fiber laser le eona e lokela ho nahana ka botsitso ba mokhoa oa transverse le phello ea ho fifala ha photon. Ka lipatlisiso, ho hlakile hore tšusumetso ea ho se tsitse ha mokhoa oa transverse ke ho futhumatsa ha fiber, 'me phello ea ho fifala ha photon e bua haholo ka hore ha fiber laser e tsoela pele ho hlahisa li-watts tse makholo kapa li-kilowatts tse' maloa tsa matla, matla a tsoang a tla bontša ka potlako ho fokotseha ha mokhoa, 'me ho na le tekanyo e itseng ea moeli holim'a tlhahiso e tsoelang pele ea matla a phahameng a fiber laser.

Le hoja lisosa tse tobileng tsa phello ea ho fifala ha photon ha li e-s'o hlalosoe ka ho hlaka hona joale, batho ba bangata ba lumela hore setsi sa bokooa ba oksijene le ho kenngoa ha tefiso ea tefiso ho ka lebisa ho etsahala ha phello ea photon e fifala. Lintlha tsena tse peli, litsela tse latelang li reretsoe ho thibela phello ea ho fifala ha photon. Joalo ka aluminium, phosphorus, joalo-joalo, e le ho qoba ho monya phetisetso ea tefiso, ebe fiber e ntlafalitsoeng e lekoa le ho sebelisoa, maemo a ikhethileng ke ho boloka matla a 3KW ka lihora tse 'maloa le ho boloka matla a 1KW a tsitsitseng lihora tse 100.
