Li-laser li fetohile karolo ea bohlokoa lits'ebetsong tsa ts'ireletso, li fana ka bokhoni boo libetsa tsa setso li ke keng tsa bapisa le tsona. Blog ena e shebisisa bohlokoa ba li-lasers ts'ireletsong, e totobatsang ho feto-fetoha ha tsona, ho nepahala, le tsoelopele ea mahlale e ba entseng motheo oa leano la sejoale-joale la sesole.
Selelekela
Ho qala ha theknoloji ea laser ho fetotse mafapha a mangata, ho kenyeletsoa likhokahano tsa mehala, bongaka, haholoholo ts'ireletso. Li-Lasers, tse nang le litšobotsi tse ikhethang tsa momahano, monochromaticity, le matla a phahameng, li butse litekanyo tse ncha tsa bokhoni ba sesole, li fana ka ho nepahala, ho utsoa le ho feto-fetoha ha maemo tse bohlokoa haholo maqheka a kajeno a ntoa le ts'ireletso.
Ho Nepaha le ho Nepaha
Li-Laser li tsebahala ka ho nepahala le ho nepahala ha tsona. Bokhoni ba bona ba ho tsepamisa maikutlo ho liphofu tse nyane libakeng tse hole bo etsa hore e be tsa bohlokoa haholo bakeng sa lits'ebetso tse joalo ka khetho ea sepheo le tataiso ea metsu. Lits'ebetso tsa laser tse nang le liqeto tse phahameng li netefatsa phano e nepahetseng ea libetsa, e fokotsa haholo ts'enyehelo ea ts'enyehelo le ho ntlafatsa litekanyetso tsa katleho ea thomo (Ahmed, Mohsin, & Ali, 2020).
Mefuta-futa ea Li-Platforms
Ho ikamahanya le maemo ha li-lasers ho pholletsa le lipolanete tse fapaneng - ho tloha ho lisebelisoa tse tšoaroang ka letsoho ho isa ho litsamaiso tse kholo tsa koloi - li totobatsa ho tenyetseha ha tsona. Li-Lasers li kenyelelitsoe ka katleho lipolaneteng tsa fatše, tsa metsing le tsa sefofane, tse sebeletsang mesebetsi e mengata e kenyelletsang ho tseba, ho fumana sepheo, le libetsa tse tobileng tsa matla bakeng sa merero e khopisang le ea ho itšireletsa. Boholo ba bona bo kopaneng le bokhoni ba ho lokisetsoa lits'ebetso tse ikhethileng li etsa hore laser e be khetho e bonolo bakeng sa ts'ebetso ea ts'ireletso (Bernatskyi & Sokolovskyi, 2022).
Puisano le Tebelo e Matlafalitsoeng
Litsamaiso tsa puisano tse thehiloeng ho laser li fana ka mokhoa o sireletsehileng le o sebetsang oa ho fetisa tlhahisoleseling, o bohlokoa bakeng sa ts'ebetso ea sesole. Monyetla o tlase oa ho thibela le ho lemoha likhokahano tsa laser li netefatsa phapanyetsano ea data e bolokehileng, ea nako ea nnete lipakeng tsa diyuniti, e matlafatsa tlhokomeliso ea maemo le khokahano. Ho feta moo, li-lasers li bapala karolo ea bohlokoa ho lebeleng le ho boeloeng hape, ho fana ka litšoantšo tse nang le liqeto tse phahameng bakeng sa pokello ea bohlale ntle le ho bonoa (Liu et al., 2020).
Libetsa tsa Matla a Tsamaisitsoeng
Mohlomong ts'ebeliso ea bohlokoa ka ho fetisisa ea li-laser ho ts'ireletso ke libetsa tsa matla tse laoloang (DEWs). Li-Lasers li ka isa matla a tsepamisitsoeng ho sepheo ho e senya kapa ho e senya, e fana ka bokhoni bo nepahetseng ba ho otla ka ts'enyehelo e nyane ea tebeletso. Nts'etsopele ea litsamaiso tsa laser tse nang le matla a phahameng bakeng sa ts'ireletso ea limisaele, tšenyo ea li-drone, le ho se sebetse ha likoloi li bonts'a bokhoni ba li-laser ho fetola sebopeho sa boitlamo ba sesole. Litsamaiso tsena li fana ka melemo e mengata ho feta libetsa tsa setso, ho kenyelletsa lebelo la ho fana ka leseli, litšenyehelo tse tlase ka ho thunngoa, le bokhoni ba ho etsa lipheo tse ngata ka nepo e phahameng (Zediker, 2022).
Lits'ebetsong tsa ts'ireletso, ho sebelisoa mefuta e fapaneng ea laser, e 'ngoe le e' ngoe e sebeletsa merero e fapaneng ea ts'ebetso e ipapisitseng le thepa le bokhoni ba eona bo ikhethang. Mona ke tse ling tsa mefuta e tsebahalang ea lasers lits'ebetsong tsa ts'ireletso:
Mefuta ea Laser e Sebelisitsoeng Sebakeng sa Tšireletso
Solid-State Lasers (SSLs): Li-lasers tsena li sebelisa mokhoa o tiileng oa ho fumana chelete, joalo ka khalase kapa lisebelisoa tsa kristale tse nang le likarolo tse sa tloaelehang tsa lefatše. Li-SSL li sebelisoa haholo bakeng sa libetsa tsa laser tse nang le matla a phahameng ka lebaka la matla a tsona a phahameng a hlahisoang, ts'ebetso e ntle le boleng ba mabone. Li ntse li lekoa le ho sebelisoa bakeng sa tšireletso ea missile, timetso ea drone, le lisebelisoa tse ling tse tobileng tsa libetsa tsa matla (Hecht, 2019).
Li-laser tsa fiber: Fiber lasers e sebelisa doped optical fiber e le mokhoa oa ho fumana chelete, e fana ka melemo ho latela maemo a bonolo, boleng ba marang-rang le katleho. Li khahleha haholo bakeng sa ts'ireletso ka lebaka la ho kopana ha tsona, ho ts'epahala, le boiketlo ba taolo ea mocheso. Li-laser tsa fiber li sebelisoa lits'ebetsong tse fapaneng tsa sesole, ho kenyeletsoa libetsa tse matla tse tsamaisoang ke matla a phahameng, sepheo sa sepheo, le lits'ebetso tsa countermeasure (Lazov, Teirumnieks, & Ghalot, 2021).
Li-Laser tsa lik'hemik'hale: Li-laser tsa lik'hemik'hale li hlahisa leseli la laser ka karabelo ea lik'hemik'hale. E 'ngoe ea li-laser tsa lik'hemik'hale tse tsebahalang haholo ho itšireletsa ke Chemical Oxygen Iodine Laser (COIL), e sebelisoang lits'ebetsong tsa laser tse tsamaisoang moeeng bakeng sa ts'ireletso ea metsu. Li-lasers tsena li ka fihlela matla a phahameng haholo 'me li sebetsa hantle libakeng tse telele (Ahmed, Mohsin, & Ali, 2020).
Li-laser tsa semiconductor:Li boetse li tsejoa e le li-laser diode, tsena ke li-laser tse momahaneng le tse sebetsang hantle tse sebelisoang mefuteng e mengata ea lits'ebetso ho tloha ho li-rangefinders le baqapi ba shebiloeng ho isa ho li-countermeasures tsa infrared le mehloli ea pompo bakeng sa litsamaiso tse ling tsa laser. Boholo ba bona bo nyane le bokhoni ba bona bo li etsa hore li tšoanelehe bakeng sa litsamaiso tsa ts'ireletso tse nkehang le tse kenngoeng ka koloing (Neukum et al., 2022).
Li-Laser tsa Vertical-Cavity Surface-Emitting Lasers (VCSELs): Li-VCSEL li ntša laser light perpendicular to the surface of the fabricated wafer 'me li sebelisoa lits'ebetsong tse hlokang tšebeliso e tlaase ea matla le lintho tse sebetsang hantle, tse kang mekhoa ea puisano le li-sensor bakeng sa likopo tsa ts'ireletso (Arafin & Jung, 2019).
Li-Laser tse putsoa:Theknoloji ea laser e putsoa e ntse e hlahlojoa bakeng sa ts'ebeliso ea ts'ireletso ka lebaka la litšobotsi tsa eona tse matlafalitsoeng tsa ho monya, tse ka fokotsang matla a laser a hlokahalang ho sepheo. Sena se etsa hore li-lasers tse putsoa e ka ba likhetho bakeng sa ts'ireletso ea drone le ts'ireletso ea metsu ea hypersonic, e fanang ka monyetla oa lits'ebetso tse nyane le tse bobebe tse nang le liphetho tse sebetsang (Zediker, 2022).
