Laser Ruby: Umgomo we operation

Lasers uqala ukuvela emashumini ambalwa eminyaka edlule, futhi lokhu ingxenye ihamba yezinkampani ezinkulu namuhla. Onjiniyela uthole zonke imishini emisha izinga, sivumele abasebenzisi kahle silisebenzise umkhuba.

Solid-isimo laser irubi akubhekwa omunye amadivayisi aphakeme kakhulu lolu hlobo, kodwa wonke amaphutha ayo, wayesalokhu uthola nasembonini msebenzi.

Uhlolojikelele

Ruby lasers ihlukaniswa njengoba amadivayisi okuqinile-state. Kuqhathaniswa zamakhemikhali igesi analogue banalo ikhono kancane okusezingeni eliphezulu. Lokhu kuchazwe umehluko izici izakhi ngawo emisebeni inikezwe. Ngokwesibonelo, okufanayo chemical lasers uyakwazi ukwakha okukhipha elikhanyayo ecucuza amakhulu kilowatts. Phakathi izici ezihlukanisa laser irubi, uqaphele ngezinga eliphezulu of monochromaticity futsi awukabumbani we ngemisebe. Ngaphezu kwalokho, amanye amamodeli ukunikeza i okuhlushwa anda yamandla okukhanya emkhathini, okuyinto kwanele ukuqhuba Fusion ngu Ukushisa ugongolo plasma.

Njengoba leli gama lisikisela, njengoba laser naphakathi asebenzayo izenzo irubi crystal okwethulwa ngesimo isilinda. Lapho lo uphela ka induku kuthiwa iphucuziwe ngendlela ekhethekile. Ukuze Ruby laser babekwazi ukunikeza esiphezulu kungenzeka amandla emisebe ye ngoba, ezinhlangothini crystal icutshungulwe kufika indiza ayefana isikhundla isihlobo komunye nomunye. Ngesikhathi esifanayo, imikhawulo kumelwe perpendicular ahlangene element. Kwezinye izimo, imikhawulo projecting kancane izibuko eminye embozwe ifilimu Kwe-dielectric Heating noma ungqimba esiliva.

Iinsetjenziswa irubi lasers

Insimbi yakhiwa ekamelweni elalinembobo, futhi umthombo energy, okuyinto ekujabulisayo athomu ye crystal. I Xenon flash isibani lingasetshenziswa njengoba flash Activator. Umthombo ukukhanya kuhlelwe endleleni oyedwa ahlangene elalinembobo kokuba simise cylindrical. Ngakolunye isici-eksisi irubi itholakala. Ngokuvamile esetshenziswa 2-25 cm izinduku ezinde.

Elalinembobo cishe zonke ukukhanya kusukela isibani iqondiswa ungene crystal. Kufanele kuqashelwe ukuthi at okushisa ephakeme, okuyinto adingekayo ukuze ukudonsa optical we crystal, bayakwazi ukusebenza, akuzona zonke izibani Xenon. Ngenxa yalesi sizathu, idivayisi irubi laser, okuyinto yakhiwa imithombo ukukhanya ngesisekelo Xenon, ibalwa imodi eqhubekayo wokusebenza, olubizwa nangokuthi ishayela. Mayelana induku, it is ngokuvamile ezenziwe isafire yokufakelwa ezingasetshenziswa oqeqeshwe ukuguqulwa nezidingo zokusebenza kuya laser.

Umgomo we operation ye-laser

Lapho isebenze idivayisi kuhlanganise umphumela isibani kombhala kwenzeka ne bandise izindlela chromium ion in the crystal, okuholela ukwanda kokungabi ngendathane iqala inani izinhlayiyana eziningi zokukhanya sasikhipha. Lapho lokhu kwenzeka ngo-ngempendulo elalinembobo olunikezwa evele esibukweni enisemikhawulweni core okuqinile. Ngakho kukhona okuphumayo ekusakazeni lokugcilwe kuto ngco.

Ubude ishayela, ngokuvamile asisikhulu kunenkosi 0,0001 kulelo isikhathi esifushane isinyathelo kuqhathaniswa nge-flash neon. Pulsed laser amandla irubi 1 J. Njengasendabeni yabase amadivayisi igesi, isimiso ukwakhiwa laser irubi futhi umphumela impendulo. Lokhu kusho ukuthi ukushuba yokucucuza ukukhanya iqala okufanele inakekelwe izibuko, uhlanganyela nohlelo elalinembobo optical.

Zindlela operation ye-laser

Ezimweni eziningi, induku irubi laser elisetshenziswa wathi ukwakha imodi pulses ngayinye amasekhondi amancane ezidlula. Ukufeza eside ubuchwepheshe umsebenzi isikhathi kwandisa amandla ukudonsa optical. Lokhu kwenziwa ngokusebenzisa ephezulu amandla izibani pulsed. Kusukela ensimini ishayela kuyanda ngenxa isikhathi ukwakha icala zikagesi e-flash tube, libhekene flat, ukusebenza irubi laser iqala ukubambezeleka ezithile ngezinye izikhathi lapho enanini lama-elementi asebenzayo idlula ukubaluleka embundwini.

Ngezinye izikhathi kukhona iloli uhlanganise isizukulwane. imihlola okunjalo kuyagcinwa njalo ngezikhathi ezithile ngemva ukwehlisa amandla amanani, okungukuthi, lapho umthamo amandla lize liba ngaphansi kwe embundwini. I laser irubi kungaba kwakuthiwa usebenza kwimodi eqhubekayo, kodwa lo msebenzi kudinga Umklamo izibani ezinamandla kakhudlwana. Empeleni, kuleli cala, abasunguli zibhekene nezinkinga efanayo kudalwa igesi lasers - isicelo nangqondo isici base ezinezici ngcono futhi ngenxa yalokho, amakhono idivayisi izivimbelo.

izinhlobo

Izinzuzo umphumela lemibono ngokucacile kakhulu obonakaliswe lasers nge elihlangana nonresonant. Ngo imiklamo efana, ezengeziwe diffusing isici sisetshenziswa, okuvumela ukuba ihlaba umkhosi okuqhubekayo imvamisa bohlu. Futhi esetshenziswa irubi laser nge-Q-esitshalweni - amaphini amabili afakiwe oyiyo, selehlile bese uncooled. Umehluko lokushisa ivumela ukwakheka imishayo ezimbili laser, okuyinto ezihlukaniswe inamandla e angstroms. Lezi imisebe kukhanye osenyameni pulsed, kanye engela ezakhiwe zithwala ezahlukene lwenani elincane.

Lapho esetshenziswa laser irubi?

lasers okunjalo zinezikhathi kahle ongaphakeme, kodwa ehlukene ukumelana ezishisayo. Futhi lezi zimfanelo kubangelwa isiqondiso ukusetshenziswa esiwusizo sokuba nezinto eziqondile lasers. Namuhla zisetshenziswe ukudalwa holography, futhi izimboni ezidinga ephezulu ukucacisa isibhakela imisebenzi izimbobo. Amadivayisi anjalo asetshenziswa imisebenzi Welding. Ngokwesibonelo, ngo-womshini izinhlaba for Logistics kwezokuxhumana satellite. Kwezokwelapha, futhi wathola indlela irubi yayo laser. Ukusetshenziswa kobuchwepheshe embonini waphinda ngenxa kungenzeka ephezulu ukucacisa ukucubungula. lasers ezinjalo zisetshenziswa njengendlela esikhundleni scalpels oyinyumba ukuthi ukwenza imisebenzi microsurgical.

isiphetho

laser Ruby nge naphakathi asebenzayo ngesikhathi esifanele waba ukugijima lokuqala lolu hlobo uhlelo. Kodwa nge ukuthuthukiswa amadivayisi enye nge gas namakhemikhali excipients kucaca ukuthi ukusebenza kwawo ube nemiphumela ethile engathandeki eziningi. Futhi lokho ingasaphathwa iqiniso lokuthi laser irubi ingenye ezinzima kunazo ngokuya yokukhiqiza. Njengoba kwanda workability yayo nezimfuneko landa izakhi akha isakhiwo. Ngenxa yalokho, ukukhiqizwa izindleko ukwanda kanye idivayisi. Nokho, ukuthuthukiswa laser onobuhle irubi crystal uye kwesisekelo salo ixhunyiwe, phakathi kokunye, ne izimfanelo eziyingqayizivele okuqinile-isimo naphakathi asebenzayo.
