Kodi laser ingadule diamondi?
Inde, ma laser amatha kudula diamondi, ndipo njira imeneyi yakhala yotchuka kwambiri mumakampani opanga diamondi pazifukwa zingapo. Kudula laser kumapereka kulondola, kugwira ntchito bwino, komanso kuthekera kodula zinthu zovuta zomwe zimakhala zovuta kapena zosatheka kuzipeza pogwiritsa ntchito njira zachikhalidwe zodulira zamakina.
Kodi njira yodulira diamondi yachikhalidwe ndi iti?
Vuto Lodula ndi Kudula Daimondi
Daimondi, popeza ndi yolimba, yofooka, komanso yokhazikika pa mankhwala, imabweretsa mavuto akulu pa njira zodulira. Njira zachikhalidwe, kuphatikizapo kudula mankhwala ndi kupukuta thupi, nthawi zambiri zimapangitsa kuti ntchito ikhale yokwera komanso kuti pakhale zolakwika zambiri, kuphatikizapo mavuto monga ming'alu, ming'alu, ndi kuwonongeka kwa zida. Popeza kufunikira kodulira molondola pogwiritsa ntchito micron, njirazi sizigwira ntchito bwino.
Ukadaulo wodula laser ukuwoneka ngati njira ina yabwino kwambiri, yopereka kudula kwachangu komanso kwapamwamba kwa zinthu zolimba komanso zosweka ngati diamondi. Njirayi imachepetsa kutentha, kuchepetsa chiopsezo cha kuwonongeka, zolakwika monga ming'alu ndi kudula, komanso kukonza bwino ntchito yokonza. Imadzitamandira ndi liwiro lachangu, ndalama zochepa zogulira zida, komanso zolakwika zochepa poyerekeza ndi njira zamanja. Yankho lofunikira la laser pakudula diamondi ndiDPSS (Diode-Pumped Solid-State) Nd: YAG (Neodymium-doped Yttrium Aluminium Garnet) laser, yomwe imatulutsa kuwala kobiriwira kwa 532 nm, zomwe zimapangitsa kuti kudula kukhale kolondola komanso kwabwino.
4 Ubwino waukulu wa kudula diamondi pogwiritsa ntchito laser
01
Kulondola Kosayerekezeka
Kudula pogwiritsa ntchito laser kumalola kudula kolondola kwambiri komanso kovuta, zomwe zimathandiza kupanga mapangidwe ovuta kwambiri komanso olondola kwambiri komanso osataya ndalama zambiri.
02
Kuchita Bwino ndi Liwiro
Njirayi ndi yachangu komanso yothandiza kwambiri, imachepetsa kwambiri nthawi yopangira ndikuwonjezera kuchuluka kwa opanga diamondi.
03
Kusinthasintha kwa Kapangidwe
Ma laser amapereka kusinthasintha kopanga mitundu yosiyanasiyana ya mawonekedwe ndi mapangidwe, zomwe zimathandiza kudula kovuta komanso kofewa komwe njira zachikhalidwe sizingakwanitse.
04
Chitetezo ndi Ubwino Wowonjezereka
Ndi kudula kwa laser, pali chiopsezo chochepetsedwa cha kuwonongeka kwa diamondi komanso mwayi wochepa wa kuvulala kwa wogwiritsa ntchito, zomwe zimapangitsa kuti kudula kwabwino komanso malo ogwirira ntchito akhale otetezeka.
DPSS Nd: Kugwiritsa Ntchito Laser ya YAG mu Kudula Daimondi
Laser ya DPSS (Diode-Pumped Solid-State) Nd:YAG (Neodymium-doped Yttrium Aluminium Garnet) yomwe imapanga kuwala kobiriwira kwa 532 nm komwe kumawirikiza kawiri imagwira ntchito kudzera munjira yovuta kwambiri yokhudza zigawo zingapo zofunika komanso mfundo zakuthupi.

- Laser ya Nd:YAG yokhala ndi chivindikiro chotseguka chowonetsa kuwala kobiriwira kwa 532 nm kowirikiza kawiri
Mfundo Yogwira Ntchito ya DPSS Laser
1. Kupompa kwa Diode:
Njirayi imayamba ndi laser diode, yomwe imatulutsa kuwala kwa infrared. Kuwala kumeneku kumagwiritsidwa ntchito "kupompa" kristalo ya Nd:YAG, kutanthauza kuti kumasangalatsa ma neodymium ayoni omwe ali mu yttrium aluminiyamu garnet crystal lattice. Laser diode imakonzedwa kuti ikhale ndi wavelength yomwe imagwirizana ndi ma absorption spectrum a ma Nd ayoni, kuonetsetsa kuti mphamvu imasamutsidwa bwino.
2. Nd:YAG Crystal:
Krustalo wa Nd:YAG ndiye njira yopezera mphamvu. Pamene ma ayoni a neodymium akhudzidwa ndi kuwala komwe kumapopa, amayamwa mphamvu ndikusamukira ku mphamvu yapamwamba. Pambuyo pa kanthawi kochepa, ma ayoni awa amabwerera ku mphamvu yochepa, ndikutulutsa mphamvu zawo zosungidwa mu mawonekedwe a ma photon. Njira imeneyi imatchedwa kutulutsa kwadzidzidzi.
[Werengani zambiri:Chifukwa chiyani tikugwiritsa ntchito kristalo ya Nd YAG ngati njira yopezera phindu mu laser ya DPSS?? ]
3. Kusintha kwa Chiwerengero cha Anthu ndi Kutulutsa Mpweya Kolimbikitsidwa:
Kuti laser igwire ntchito, payenera kukhala kusintha kwa kuchuluka kwa anthu, komwe ma ayoni ambiri amakhala mu excited state kuposa mu lower energy state. Pamene ma photon akudumphadumpha pakati pa magalasi a laser cavity, amalimbikitsa ma Nd ayoni osangalatsidwa kuti atulutse ma photon ambiri a gawo lomwelo, njira, ndi kutalika kwa nthawi. Njirayi imadziwika kuti stimulated emission, ndipo imakulitsa mphamvu ya kuwala mkati mwa kristalo.
4. Mphepete mwa Laser:
Mphepete mwa laser nthawi zambiri mumakhala magalasi awiri kumapeto kwa kristalo wa Nd:YAG. Galasi limodzi limawala kwambiri, ndipo linalo limawala pang'ono, zomwe zimapangitsa kuti kuwala kutuluke pamene laser ikutuluka. Mphepete mwa laser imawala bwino ndi kuwalako, zomwe zimapangitsa kuti kuwalako kukhale kowonjezereka kudzera mu mafunde obwerezabwereza omwe amatulutsidwa.
5. Kuwirikiza kawiri pafupipafupi (Kupanganso kwachiwiri kwa Harmonic):
Kuti asinthe kuwala kwa ma frequency (nthawi zambiri 1064 nm yotulutsidwa ndi Nd:YAG) kukhala kuwala kobiriwira (532 nm), kristalo wowirikiza kawiri (monga KTP - Potassium Titanyl Phosphate) amayikidwa munjira ya laser. Kristalo iyi ili ndi mawonekedwe osalunjika omwe amalola kuti itenge ma fotoni awiri a kuwala koyambirira kwa infrared ndikuwaphatikiza kukhala fotoni imodzi yokhala ndi mphamvu yowirikiza kawiri, motero, theka la kutalika kwa mafunde a kuwala koyambirira. Njirayi imadziwika kuti second harmonic generation (SHG).
6. Kutulutsa kwa Kuwala Kobiriwira:
Zotsatira za kuwirikiza kawiri kumeneku ndi kutulutsa kwa kuwala kobiriwira kowala pa 532 nm. Kuwala kobiriwira kumeneku kungagwiritsidwe ntchito pazinthu zosiyanasiyana, kuphatikizapo ma laser pointers, ma laser shows, fluorescence excitation mu microscopy, ndi njira zachipatala.
Njira yonseyi ndi yothandiza kwambiri ndipo imalola kupanga kuwala kobiriwira kwamphamvu kwambiri komanso kogwirizana mumtundu wocheperako komanso wodalirika. Chinsinsi cha kupambana kwa laser ya DPSS ndi kuphatikiza kwa solid-state gain media (Nd:YAG crystal), kupompa bwino kwa diode, komanso kuwirikiza kawiri pafupipafupi kuti mukwaniritse kutalika kwa mafunde komwe mukufuna.
