Gwero la laser ndiye gawo lofunikira pamakina onse a laser. Lili ndi magulu osiyanasiyana. Mwachitsanzo, kutali infuraredi laser, laser looneka, X-ray laser, UV laser, ultrafast laser, etc.. Ndipo lero, ife makamaka kuganizira ultrafast laser ndi UV laser.
Kukula kwa ultrafast laser
Pamene teknoloji ya laser ikupitilira kukula, laser ultrafast idapangidwa. Imakhala ndi ma pulse afupi-fupi kwambiri ndipo imatha kuwunikira kwambiri pakuwala kwambiri ndi mphamvu yocheperako. Mosiyana ndi laser yachikhalidwe ya pulse ndi laser yopitilira muyeso, laser ya Ultrafast imakhala ndi kugunda kwa laser kopitilira muyeso, komwe kumatsogolera 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 imagwiritsidwa ntchito pokonza molondola
Ultrafast laser imatha kukwaniritsa kudula koyera ndikupambana’t kuwononga malo ozungulirawo 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 kwapanga kale laser ya ultrafast“adatuluka” kuchokera ku 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. Kwa zida zosalimba monga magalasi ndi zoumba, kukonza kwawo kumafuna kulondola kwambiri komanso kulondola. Ndipo laser yachangu kwambiri imatha kuchita izi. M'magulu azachipatala, zipatala zambiri zimatha kuchita opaleshoni ya cornea, opaleshoni yamtima ndi maopaleshoni ena ovuta.
UV laser ndi abwino kwambiri kafukufuku wa sayansi, makampani ndi OEM dongosolo Integrated chitukuko
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 cheza cha 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 mawonekedwe amfupi kwambiri& pulse m'lifupi ndi kutsika kwa M2, kotero imatha kupanga malo owunikira kwambiri a laser ndikusunga kutentha kocheperako komwe kumakhudza madera kuti athe kukwaniritsa makina ang'onoang'ono ang'onoang'ono. Kutengera mphamvu yayikulu kuchokera ku laser ya UV, zinthu zimatha kusungunuka mwachangu. Choncho carbonization akhoza kuchepetsa.
Kutalika kwa mawonekedwe a UV laser ndi pansi pa 0.4μm, zomwe zimapangitsa UV laser chisankho chabwino 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.
Kukula kwa zoweta UV laser
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 kwakukulu uku 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 makamaka kuziziritsa UV laser ndi ultrafast laser motsatana. Kukhazikika kwawo kwa kutentha kungakhale mpaka±0.2℃ ndi±0.1℃. Kukhazikika kwamtunduwu kumatha kusunga laser ya UV ndi laser ultrafast pamlingo wokhazikika wotentha. Simuyeneranso kuda nkhawa kuti kusintha kwamafuta 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
