Gwero la laser ndiye gawo lofunikira pamakina onse a laser. Lili ndi magulu osiyanasiyana. Mwachitsanzo, laser infuraredi kutali, laser looneka, X-ray laser, UV laser, ultrafast laser, etc.. Ndipo lero, ife makamaka kuganizira ultrafast laser ndi UV laser.
Pamene teknoloji ya laser ikupitiriza kukula, laser ultrafast laser inapangidwa. Imakhala ndi ma pulse afupi-fupi kwambiri ndipo imatha kuwunikira kwambiri pamlingo wapamwamba kwambiri ndi mphamvu yocheperako. Mosiyana ndi laser yachikhalidwe ya pulse ndi laser yopitilira, ultrafast laser imakhala ndi pulse yaifupi yayifupi ya laser, yomwe imatsogolera kukula kwakukulu kwa sipekitiramu. Ikhoza kuthetsa mavuto omwe njira zachikhalidwe zimakhala zovuta kuthetsa ndipo zimakhala ndi luso lodabwitsa la processing, khalidwe ndi luso. Zimakopa pang'onopang'ono maso a opanga makina a laser.
Ultrafast laser imatha kukwaniritsa kudula koyera ndipo sikungawononge malo odulidwawo kuti apange m'mphepete mwake. Choncho, n'kopindulitsa kwambiri pokonza galasi, safiro, zipangizo kutentha tcheru, polima ndi zina zotero. Kupatula apo, imagwiranso ntchito yofunika kwambiri pa maopaleshoni omwe amafunikira kulondola kwambiri.
Kusinthidwa kosalekeza kwaukadaulo wa laser kwapangitsa kale laser ya ultrafast "kutuluka" mu labotale ndikulowa m'mafakitale ndi azachipatala. Kupambana kwa laser ultrafast kumadalira kuthekera kwake kuyang'ana mphamvu yowunikira mkati mwa picosecond kapena femtosecond mulingo waung'ono kwambiri.
M'mafakitale, laser ultrafast ndi yoyeneranso pokonza zitsulo, semiconductor, galasi, kristalo, zoumba ndi zina zotero. Pazinthu zosaoneka ngati galasi ndi zoumba, kukonza kwawo kumafuna kulondola kwambiri komanso kulondola. Ndipo laser yachangu kwambiri imatha kuchita izi. M'chipatala, zipatala zambiri zimatha kuchita opaleshoni ya cornea, opaleshoni yamtima ndi maopaleshoni ena ovuta.
Kugwiritsa ntchito kwakukulu kwa laser ya UV kumaphatikizapo kafukufuku wasayansi ndi zida zopangira mafakitale. Pakadali pano, amagwiritsidwa ntchito kwambiri paukadaulo wamakina ndi zida zamankhwala ndi zida zowumitsa zomwe zimafuna kuwala kwa ultraviolet. DPSS UV laser yochokera pa Nd:YAG/Nd:YVO4 crystal ndiye njira yabwino kwambiri yopangira ma micromachining, motero ili ndi ntchito yayikulu pakukonza PCB ndi zamagetsi zamagetsi.
Laser ya UV imakhala ndi utali wamtali wamtali wamtali & pulse m'lifupi ndi kutsika kwa M2, kotero imatha kupanga malo owunikira kwambiri a laser ndikusunga kutentha kochepa kwambiri komwe kumakhudza malo kuti mukwaniritse makina ang'onoang'ono m'malo ochepa. Kutengera mphamvu yayikulu kuchokera ku laser ya UV, zinthu zimatha kutuluka mwachangu kwambiri. Choncho carbonization akhoza kuchepetsa.
Kutalika kwa laser kwa UV kumakhala pansi pa 0.4μm, zomwe zimapangitsa UV laser kukhala chisankho choyenera pokonza polima. Mosiyana ndi infuraredi kuwala processing, UV laser micro-machining si kutentha mankhwala. Kupatula apo, zida zambiri zimatha kuyamwa kuwala kwa UV mosavuta kuposa kuwala kwa infrared. Momwemonso polima.
Kuphatikiza pa mfundo yakuti mitundu yakunja monga Trumpf, Coherent ndi Inno imayang'anira msika wapamwamba kwambiri, opanga ma laser akunyumba a UV akukumananso ndikukula kolimbikitsa. Zogulitsa zapakhomo monga Huaray, RFH ndi Inngu zikukula kwambiri pachaka.
Ziribe kanthu kaya ndi ultrafast laser kapena UV laser, onse amagawana chinthu chimodzi chofanana - kulondola kwambiri. Ndiko kulondola kwapamwamba kumeneku komwe kumapangitsa kuti mitundu iwiri ya laser iyi ikhale yotchuka kwambiri pamsika wovuta. Komabe, amakhudzidwa kwambiri ndi kusintha kwa kutentha. Kusinthasintha pang'ono kwa kutentha kungayambitse kusiyana kwakukulu pakukonza. Chozizira bwino cha laser chingakhale chisankho chanzeru.
S&A Mndandanda wa Teyu CWUL ndi zoziziritsa kukhosi za CWUP zidapangidwira kuti aziziziritsa laser ya UV ndi laser yachangu kwambiri motsatana. Kukhazikika kwawo kutentha kumatha kufika ± 0.2 ℃ ndi ± 0.1 ℃. Kukhazikika kwamtunduwu kumatha kusunga laser ya UV ndi laser ultrafast pamlingo wokhazikika wotentha. Simuyeneranso kuda nkhawa kuti kusintha kwa kutentha kungakhudze magwiridwe antchito a laser. Kuti mudziwe zambiri za mndandanda wa CWUP ndi CWUL mndandanda wa laser coolers, dinani https://www.chillermanual.net/uv-laser-chillers_c4
