Laser Diode Bar: Matla a Core ka morao ho Lisebelisoa tsa Laser tse Matla a Phahameng

Ha theknoloji ea laser e ntse e tsoela pele ho fetoha, mefuta ea mehloli ea laser e ntse e fapana le ho feta. Har'a tsona, laser diode bar e hlahella ka matla a eona a phahameng, sebopeho se kopaneng, le taolo e ntle ea mocheso, e e etsa karolo ea bohlokoa mafapheng a kang ts'ebetso ea indasteri, botle ba bongaka, mehloli ea pompo le lipatlisiso tsa mahlale.

1. Laser Diode Bar ke eng?

Laser diode bar, eo hape e tsejoang e le laser diode array, ke sesebelisoa sa laser semiconductor ea matla a phahameng se entsoeng ka ho kopanya likarolo tse ngata tsa laser-emitting holim'a substrate e le 'ngoe e tloaelehileng. Ka tloaelo, karolo e 'ngoe le e' ngoe e ntšang e ka ba bophara ba li-micrometer tse 100, ha bophara bohle ba bar bo ka tloha ho limilimithara tse 'maloa ho isa ho lisentimitara. Hobane lisebelisoa tsa laser tse ngata li hlophisitsoe ka lehlakore, li-bars tsa laser diode li ka fana ka matla a sa khaotseng kapa a sisinyehang ho tloha ho mashome a watts ho ea ho kilowatt.

2. Likarolo tsa Bohlokoa

① Matla a Matla a Phahameng

Lisebelisoa tsa laser diode li kopanya li-emitter tse ngata sebakeng se kopaneng ho fana ka matla a phahameng haholo, e leng se etsang hore e be tse loketseng lits'ebetso tse hlokang matla a mangata.

② Taolo e Ntle ea Thermal

Sebopeho sa bar se tsamaellana le mahlale a fapaneng a ho paka, joalo ka AuSn (gold-tin), all-indium, le hybrid packaging, e matlafatsang phepelo ea mocheso, e lelefatsa bophelo ba sesebelisoa, le ho netefatsa ts'ebetso e tsitsitseng ea nako e telele.

③ Li-wavelengths tse ikhethileng

Ho ipapisitsoe le ts'ebeliso, lisebelisoa tsa laser diode li ka etsoa bakeng sa maqhubu a fapaneng a ts'ebetso, joalo ka 808 nm, 915 nm, 940 nm le 976 nm. Customization e khethehileng ea wavelength e boetse e fumaneha ho fihlela litlhoko tse ikhethang tsa lisebelisoa le litsamaiso tse fapaneng.

④ Flexible Beam Shaping

Le hoja boleng ba mahlaseli a lisebelisoa tsa laser diode ka kakaretso bo le tlase ho feta ba laser-mode e le 'ngoe, lisebelisoa tsa optical tse kang li-lens arrays, fiber coupling le micro-lens systems li ka sebelisoa ho kopana kapa ho tsepamisa mohopolo holim'a sefate, ho matlafatsa kopanyo le ho fetoha habonolo lits'ebetsong tsa tsamaiso.

3. Libaka tsa Kopo

① Tlhahiso ea Liindasteri

E sebelisoa ho tjheseletsa ka polasetiki, kalafo ea mocheso oa tšepe, ho hloekisa ka laser le ho tšoaea, mekoallo ea laser diode e fana ka tekanyo e ntle ea ts'ebetso ea litšenyehelo lits'ebetsong tse hlokang mehloli ea matla a phahameng a laser.

② Bongaka le Bokhabane

Mohlala, li-laser diode tsa 808 nm li sebelisoa haholo lisebelisoa tsa laser tsa ho tlosa moriri. Li fana ka matla a phahameng le botebo ba ho kenella ka mokhoa o itekanetseng, ka katleho li senya li-follicle tsa moriri ntle le ho senya lisele tse potolohileng.

③ Mehloli ea Pompo bakeng sa Fiber Lasers

Lits'ebetsong tsa laser fiber ea matla a phahameng, mekoallo ea laser diode hangata e sebelisoa e le mehloli ea pompo ho hlasimolla likhoele tsa Yb-doped kapa Er-doped, li bapala karolo ea bohlokoa ho aheng lisebelisoa tsa laser tse matla haholo.

④ Patlisiso ea Mahlale le Tšireletso

Lisebelisoa tsa laser diode le tsona li sebelisoa haholo mahlaleng a tsoetseng pele joalo ka liteko tsa fisiks ea matla a phahameng, LiDAR, le likhokahano tsa laser, ka lebaka la tlhahiso ea tsona e tsitsitseng le thepa eo u ka e khethang.

Ha litlhoko tsa ts'ebetso ea litsamaiso tsa laser li ntse li eketseha, mekoallo ea laser diode e ntse e tsoela pele ho ea matla a phahameng, ho ts'epahala ho hoholo, lintlha tse nyane tsa sebopeho le litšenyehelo tse tlase. Joalo ka karolo ea bohlokoa lits'ebetsong tsa ts'ebeliso ea laser, li-bar diode tsa laser li ntse li amoheloa ka bongata libakeng tsa theknoloji e phahameng. Ka tsoelo-pele e tsoelang pele ea theknoloji le ketane ea indasteri e ntseng e hola, li-bar diode tsa laser li lebelletsoe ho natefeloa ke menyetla e pharalletseng ea mmaraka le ho nka karolo ea maano nakong e tlang.
