Njira yokonzera bwino ya laser yolimba

Njira yokonzera bwinolaser yolimba
Kukonza ma lasers olimba kumaphatikizapo zinthu zingapo, ndipo izi ndi zina mwa njira zazikulu zokonzera zinthu:
Chimodzi, Mawonekedwe abwino kwambiri a kusankha kwa kristalo wa laser: strip: malo akuluakulu otaya kutentha, othandiza kuyang'anira kutentha. Ulusi: chiŵerengero chachikulu cha malo pamwamba pa voliyumu, mphamvu yayikulu yosamutsa kutentha, koma samalani mphamvu ndi kukhazikika kwa ulusi. Pepala: Kukhuthala kwake ndi kochepa, koma mphamvu yake iyenera kuganiziridwa poyika. Ndodo yozungulira: malo otaya kutentha nawonso ndi akulu, ndipo kupsinjika kwa makina sikukhudzidwa kwambiri. Kuchuluka kwa doping ndi ma ions: Konzani kuchuluka kwa doping ndi ma ions a kristalo, kusintha kwambiri kuyamwa ndi kusintha kwa mphamvu ya kristalo kukhala kuwala kwa pampu, ndikuchepetsa kutaya kutentha.
Ndiponso, njira yowongolera kutentha: kuzizira kwamadzimadzi ndi kuzizira kwa mpweya ndi njira zodziwika bwino zochotsera kutentha, zomwe ziyenera kusankhidwa malinga ndi momwe zimagwiritsidwira ntchito. Ganizirani zinthu zomwe zili mu makina oziziritsira (monga mkuwa, aluminiyamu, ndi zina zotero) ndi kutentha kwake kuti muwongolere kutentha. Kuwongolera kutentha: Kugwiritsa ntchito ma thermostat ndi zida zina kuti laser ikhale pamalo okhazikika otentha kuti muchepetse kusinthasintha kwa kutentha pamagwiridwe antchito a laser.
Kuphatikiza apo, Kukonza bwino njira yopopera pompu: pompu yam'mbali, pompu ya ngodya, pompu ya pamwamba ndi pompu yomaliza ndi njira zodziwika bwino zopopera. Pompu yomaliza ili ndi ubwino wolumikizana bwino, kusintha kwakukulu komanso kuzizira konyamulika. Kupopera m'mbali kumathandiza pakukweza mphamvu ndi kufanana kwa kuwala. Kupopera m'mbali kumaphatikiza zabwino zopopera nkhope ndi pompu yam'mbali. Kuyang'ana pamwala wa pompu ndi kugawa mphamvu: Konzani kuyang'ana ndi kugawa mphamvu kwa mwala wa pompu kuti muwonjezere kugwira ntchito bwino ndikuchepetsa kutentha.
Chabwino, Kapangidwe kabwino ka resonator ka resonator ndi cholumikizira chotulutsa: sankhani kuwunikira koyenera kwa galasi la cavity ndi kutalika kwa cavity kuti mukwaniritse kutulutsa kwa laser kwa multi-mode kapena single-mode. Kutulutsa kwa single longitudinal mode kumachitika mwa kusintha kutalika kwa cavity, ndipo mphamvu ndi mtundu wa wavefront zimawongoleredwa. Kukonza bwino kwa cholumikizira chotulutsa: Sinthani transmittance ndi malo a galasi lolumikizira chotulutsa kuti mukwaniritse kutulutsa kwamphamvu kwalaser.
Ndipo, Kukonza Zinthu ndi Njira Kusankha Zinthu: Malinga ndi zosowa za laser, sankhani zipangizo zoyenera zopezera zinthu monga Nd:YAG, Cr:Nd:YAG, ndi zina zotero. Zipangizo zatsopano monga zoumba zowonekera bwino zili ndi ubwino wa nthawi yochepa yokonzekera komanso kugwiritsa ntchito mankhwala osokoneza bongo mosavuta, zomwe ziyenera kusamalidwa. Njira yopangira: Kugwiritsa ntchito zipangizo zokonzera zinthu molondola komanso ukadaulo wotsimikizira kuti zinthu za laser ndi zolondola. Makina okonza zinthu ndi zomanga bwino zimatha kuchepetsa zolakwika ndi kutayika munjira yowunikira ndikukweza magwiridwe antchito onse a laser.
Kuyesa, Kuyesa ndi kuyesa magwiridwe antchito Zizindikiro zowunikira magwiridwe antchito: kuphatikiza mphamvu ya laser, kutalika kwa nthawi, mawonekedwe a kutsogolo kwa mafunde, mtundu wa beam, kukhazikika, ndi zina zotero. Zipangizo zoyesera: Kugwiritsa ntchitomita yamagetsi ya kuwala, spectrometer, wave front sensor ndi zida zina zoyesera magwiridwe antchito a laser. Kudzera mu kuyesa, mavuto a laser amapezeka pakapita nthawi ndipo njira zoyenera zimatengedwa kuti ziwongolere magwiridwe antchito.
Chimodzi, Zatsopano ndi ukadaulo wopitilira Kutsata zatsopano zaukadaulo: samalani ndi zomwe zikuchitika posachedwa paukadaulo ndi zomwe zikuchitika pakukula kwa laser, ndikuyambitsa ukadaulo watsopano, zida zatsopano ndi njira zatsopano. Kusintha kosalekeza: Kusintha kosalekeza ndi zatsopano pamaziko omwe alipo, ndikupititsa patsogolo magwiridwe antchito ndi mtundu wa laser nthawi zonse.
Mwachidule, kukonza bwino ma laser a solid-state kuyenera kuyambira pazinthu zambiri, monga laser crystal, thermal management, pumping mode, resonator ndi output coupling, zinthu ndi njira, komanso kuwunika magwiridwe antchito ndi kuyesa. Kudzera mu mfundo zonse komanso kusintha kosalekeza, magwiridwe antchito ndi mtundu wa ma laser a solid-state amatha kupititsidwa patsogolo nthawi zonse.
