Gwero la laser ndiye gawo lofunika kwambiri la machitidwe onse a laser. Lili ndi magulu osiyanasiyana. Mwachitsanzo, laser ya infrared yakutali, laser yowoneka, laser ya X-ray, laser ya UV, laser ya ultrafast, ndi zina zotero. Ndipo lero, tikuyang'ana kwambiri pa laser ya ultrafast ndi laser ya UV.
Pamene ukadaulo wa laser ukupitilira kukula, laser yothamanga kwambiri idapangidwa. Ili ndi pulse yapadera ya ultra-short pulse ndipo imatha kufika pamlingo wapamwamba kwambiri wokhala ndi mphamvu yochepa ya pulse. Mosiyana ndi laser yachikhalidwe ya pulse ndi laser yopitilira mafunde, laser yothamanga kwambiri ili ndi pulse ya ultra-short laser, zomwe zimapangitsa kuti ikhale ndi spectrum width yayikulu. Imatha kuthetsa mavuto omwe njira zachikhalidwe zimakhala zovuta kuthetsa ndipo ili ndi luso lodabwitsa lokonza, khalidwe, komanso magwiridwe antchito. Pang'onopang'ono ikukopa maso a opanga makina a laser.
Laser yothamanga kwambiri imatha kudula bwino ndipo siiwononga malo ozungulira malo odulidwawo kuti ipange m'mbali zozungulira. Chifukwa chake, ndi yothandiza kwambiri pokonza magalasi, safiro, zinthu zomwe zimakhudzidwa ndi kutentha, polima ndi zina zotero. Kupatula apo, imagwiranso ntchito yofunika kwambiri pa opaleshoni yomwe imafunikira kulondola kwambiri.
Kusintha kosalekeza kwa ukadaulo wa laser kwapangitsa kale kuti ultrafast laser "ituluke" mu labotale ndikulowa m'magawo azamalonda ndi azachipatala. Kupambana kwa ultrafast laser kumadalira kuthekera kwake kuyang'ana mphamvu ya kuwala mkati mwa mulingo wa picosecond kapena femtosecond m'dera laling'ono kwambiri.
Mu gawo la mafakitale, laser yothamanga kwambiri ndi yoyeneranso kukonza zitsulo, semiconductor, galasi, kristalo, zoumba ndi zina zotero. Pazinthu zofooka monga galasi ndi zoumba, kukonza kwawo kumafuna kulondola kwambiri komanso kulondola. Ndipo laser yothamanga kwambiri ingachite bwino kwambiri. Mu gawo la zamankhwala, zipatala zambiri tsopano zimatha kuchita opaleshoni ya cornea, opaleshoni ya mtima ndi maopaleshoni ena ovuta.
Kugwiritsa ntchito kwakukulu kwa laser ya UV kumaphatikizapo kafukufuku wasayansi ndi zida zopangira mafakitale. Pakadali pano, imagwiritsidwa ntchito kwambiri paukadaulo wamankhwala ndi zida zamankhwala komanso zida zoyeretsera zomwe zimafuna kuwala kwa ultraviolet. DPSS UV laser yochokera ku Nd:YAG/Nd:YVO4 crystal ndiyo chisankho chabwino kwambiri pa micromachining, kotero imagwiritsidwa ntchito kwambiri pokonza PCB ndi zida zamagetsi.
Laser ya UV ili ndi kutalika kwa mafunde ndi m'lifupi mwake komanso M2 yotsika, kotero imatha kupanga malo owunikira a laser olunjika kwambiri ndikusunga malo ochepa kwambiri omwe amakhudza kutentha kuti ikwaniritse makina olondola kwambiri m'malo ochepa. Potengera mphamvu zambiri kuchokera ku laser ya UV, zinthu zimatha kuphwa mwachangu kwambiri. Chifukwa chake carbonization imatha kuchepa.
Kutalika kwa mphamvu ya kuwala kwa UV laser kuli pansi pa 0.4μm, zomwe zimapangitsa UV laser kukhala chisankho chabwino kwambiri chogwiritsira ntchito polima. Mosiyana ndi kukonza kuwala kwa infrared, UV laser micro-machining si mankhwala otentha. Kupatula apo, zinthu zambiri zimatha kuyamwa kuwala kwa UV mosavuta kuposa kuwala kwa infrared. Momwemonso polima.
Kuwonjezera pa mfundo yakuti mitundu yakunja monga Trumpf, Coherent ndi Inno ndi yomwe ikutsogolera msika wapamwamba, opanga ma laser a UV akukulirakulira. Mitundu yakunja monga Huaray, RFH ndi Inngu ikugulitsidwa kwambiri pachaka.
Kaya ndi laser yothamanga kwambiri kapena UV laser, zonse ziwiri zimafanana - kulondola kwambiri. Ndi kulondola kwakukulu kumeneku komwe kumapangitsa mitundu iwiriyi ya laser kukhala yotchuka kwambiri m'makampani ovuta. Komabe, ndi osavuta kwambiri kusintha kwa kutentha. Kusintha pang'ono kwa kutentha kungayambitse kusiyana kwakukulu pakugwira ntchito bwino. Choziziritsira cha laser choyenera chingakhale chisankho chanzeru.
Ma S&A Teyu CWUL series ndi ma CWUP laser coolers apangidwa makamaka kuti aziziritse UV laser ndi ultrafast laser motsatana. Kukhazikika kwawo kutentha kumatha kufika ±0.2℃ ndi ±0.1℃. Mtundu uwu wa kukhazikika kwakukulu ukhoza kusunga UV laser ndi ultrafast laser pa kutentha kokhazikika kwambiri. Simuyeneranso kuda nkhawa kuti kusintha kwa kutentha kungakhudze magwiridwe antchito a laser. Kuti mudziwe zambiri za CWUP series ndi CWUL series laser coolers, dinani https://www.chillermanual.net/uv-laser-chillers_c4
