Kodi laser angadule diamondi?
Inde, ma lasers amatha kudula diamondi, ndipo njira iyi yatchuka kwambiri pamsika wa diamondi pazifukwa zingapo. Kudula kwa laser kumapereka kulondola, kuchita bwino, komanso kuthekera kopanga mabala ovuta omwe ndi ovuta kapena osatheka kukwaniritsa ndi njira zachikhalidwe zamakina.
Kodi njira yanthawi zonse yodula diamondi ndi iti?
Chovuta Pakudula ndi Kucheka Daimondi
Daimondi, pokhala yolimba, yosasunthika, komanso yosasunthika pamankhwala, imabweretsa zovuta zazikulu pakudula. Njira zachikale, kuphatikizapo kudula kwa mankhwala ndi kupukuta thupi, nthawi zambiri kumabweretsa kukwera mtengo kwa ogwira ntchito ndi zolakwika, kuphatikizapo ming'alu, tchipisi, ndi kuvala zida. Poganizira kufunikira kwa kudulidwa kwa ma micron-level kulondola, njirazi ndizochepa.
Ukadaulo wodulira laser umatuluka ngati njira yabwino kwambiri, yopereka kuthamanga kwambiri, kudula kwapamwamba kwazinthu zolimba, zolimba ngati diamondi. Njirayi imachepetsa kutenthedwa kwa kutentha, kuchepetsa chiopsezo cha kuwonongeka, zolakwika monga ming'alu ndi kupukuta, ndikuthandizira kukonza bwino. Iwo akudzitamandira mofulumira liwiro, kutsika mtengo zipangizo, ndi zolakwa kuchepetsa poyerekeza ndi njira Buku. Njira yofunika kwambiri ya laser pakudula diamondi ndiDPSS (Diode-Pumped Solid-State) Nd: YAG (Neodymium-doped Yttrium Aluminium Garnet) laser, yomwe imatulutsa kuwala kobiriwira kwa 532 nm, kupititsa patsogolo kudula ndi khalidwe.
4 Ubwino waukulu wa laser diamondi kudula
01
Zosayerekezeka Precision
Kudula kwa laser kumalola kudulidwa kolondola kwambiri komanso kosavuta, kupangitsa kuti pakhale mapangidwe ovuta kwambiri olondola kwambiri komanso zinyalala zochepa.
02
Kuchita bwino ndi Kuthamanga
Njirayi ndi yachangu komanso yothandiza kwambiri, imachepetsa kwambiri nthawi yopanga komanso kuchulukitsa kwa opanga diamondi.
03
Zosiyanasiyana mu Design
Ma laser amapereka kusinthasintha kuti apange mawonekedwe osiyanasiyana ndi mapangidwe, kutengera mabala ovuta komanso osakhwima omwe njira zachikhalidwe sizingakwaniritse.
04
Chitetezo & Ubwino Wowonjezera
Ndi laser kudula, pali chiwopsezo chochepa cha kuwonongeka kwa diamondi komanso mwayi wocheperako wakuvulala kwa opareshoni, kuwonetsetsa kudulidwa kwapamwamba komanso malo otetezeka ogwirira ntchito.
DPSS Nd: Kugwiritsa Ntchito Laser YAG mu Kudula Daimondi
Laser ya DPSS (Diode-Pumped Solid-State) Nd:YAG (Neodymium-doped Yttrium Aluminium Garnet) yomwe imapanga kuwala kobiriwira kawiri kawiri ka 532 nm imagwira ntchito mwaukadaulo wokhudza zigawo zingapo zazikulu ndi mfundo zakuthupi.

Mfundo Yogwira Ntchito ya DPSS Laser
1. Kupopa kwa Diode:
Njirayi imayamba ndi laser diode, yomwe imatulutsa kuwala kwa infuraredi. Kuwala kumeneku kumagwiritsidwa ntchito "kupopa" kristalo wa Nd:YAG, kutanthauza kuti imasangalatsa ma ion a neodymium ophatikizidwa mu yttrium aluminium garnet crystal lattice. Laser diode imasinthidwa kukhala kutalika komwe kumafanana ndi mawonekedwe a mayamwidwe a Nd ions, kuwonetsetsa kusuntha kwamphamvu kwamphamvu.
2. Nd:YAG Crystal:
The Nd: YAG crystal ndiye njira yopezera phindu. Ma ion a neodymium akasangalatsidwa ndi kuwala kopopa, amatenga mphamvu ndikupita kumalo okwera kwambiri. Pakapita nthawi yochepa, ma ion awa amabwerera ku mphamvu yochepa, kutulutsa mphamvu zawo zosungidwa mu mawonekedwe a photons. Izi zimatchedwa kutulutsa kochitika modzidzimutsa.
[Werengani zambiri:Chifukwa chiyani tikugwiritsa ntchito kristalo ya Nd YAG ngati njira yopezera DPSS laser? ]
3. Kusintha kwa Anthu ndi Kutulutsa Kokoka:
Kuti zochita za laser zichitike, kusinthika kwa anthu kuyenera kuchitika, pomwe ma ion ambiri ali pachisangalalo kuposa momwe amachitira mphamvu zochepa. Pamene ma photon amabwerera mmbuyo ndi mtsogolo pakati pa magalasi a laser cavity, amalimbikitsa ma ion a Nd okondwa kutulutsa mafotoni ambiri a gawo lomwelo, njira, ndi kutalika kwa mafunde. Njirayi imadziwika kuti stimulated emission, ndipo imakulitsa mphamvu ya kuwala mkati mwa kristalo.
4. Laser Cavity:
Laser cavity nthawi zambiri imakhala ndi magalasi awiri kumapeto kwa Nd:YAG crystal. Galasi limodzi limayang'ana kwambiri, ndipo linalo limayang'ana pang'ono, zomwe zimapangitsa kuti kuwala kwina kutuluke ngati laser imatulutsa. Mphunoyo imamveka ndi kuwala, ndikukulitsa kupyolera mu maulendo obwerezabwereza a kutulutsa kolimbikitsa.
5. Kuwirikiza kawiri (Mbadwo Wachiwiri wa Harmonic):
Kuti musinthe kuwala kofunikira pafupipafupi (nthawi zambiri 1064 nm yotulutsidwa ndi Nd:YAG) kukhala kuwala kobiriwira (532 nm), kristalo wowirikiza kawiri (monga KTP - Potassium Titanyl Phosphate) imayikidwa munjira ya laser. Krustalo ili ndi mawonekedwe owoneka bwino omwe amalola kuti atenge zithunzi ziwiri za kuwala koyambirira kwa infrared ndikuziphatikiza mu photon imodzi yokhala ndi mphamvu ziwiri, motero, theka la kutalika kwa kuwala koyambirira. Njirayi imadziwika kuti Second harmonic generation (SHG).
6. Kutulutsa kwa Kuwala Kobiriwira:
Zotsatira za kuwirikiza kawiri uku ndikutulutsa kwa kuwala kobiriwira kowala pa 532 nm. Kuwala kobiriwira kumeneku kumatha kugwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikiza zolozera za laser, mawonedwe a laser, chisangalalo cha fluorescence mu microscope, ndi njira zamankhwala.
Njira yonseyi ndi yothandiza kwambiri ndipo imalola kuti pakhale kuwala kwamphamvu kwambiri, kogwirizana kobiriwira mumtundu wokhazikika komanso wodalirika. Chinsinsi cha kupambana kwa laser ya DPSS ndi kuphatikiza kwa media-state gain media (Nd: YAG crystal), kupopera koyenera kwa diode, komanso kuwirikiza kawiri kawiri kuti mukwaniritse kutalika komwe mukufuna.
