Kodi laser CW DPSS ndi chiyani? Kuwonongeka kwa Tanthauzo

Mafunde Opitirira (CW):Izi zikutanthauza njira yogwiritsira ntchito laser. Mu mawonekedwe a CW, laser imatulutsa kuwala kosasunthika, kosalekeza, mosiyana ndi ma lasers othamanga omwe amatulutsa kuwala pakuphulika. Ma lasers a CW amagwiritsidwa ntchito ngati kuwala kosalekeza, kosasunthika kumafunika, monga kudula, kuwotcherera, kapena kujambula.

Kupopa kwa Diode:Mu ma lasers opopedwa ndi diode, mphamvu yomwe imagwiritsidwa ntchito kusangalatsa sing'anga ya laser imaperekedwa ndi ma semiconductor laser diode. Ma diode awa amatulutsa kuwala komwe kumatengedwa ndi laser sing'anga, kusangalatsa maatomu omwe ali mkati mwake ndikuwalola kutulutsa kuwala kogwirizana. Kupopa kwa diode kumakhala kothandiza komanso kodalirika poyerekeza ndi njira zakale zopopera, monga nyali, ndipo zimapangitsa kuti pakhale mapangidwe olimba komanso olimba a laser.

Solid-State Laser:Mawu oti "solid-state" amatanthauza mtundu wa njira yopezera phindu yomwe imagwiritsidwa ntchito mu laser. Mosiyana ndi ma laser a gasi kapena amadzimadzi, ma lasers olimba-boma amagwiritsa ntchito zinthu zolimba ngati sing'anga. Sing'anga iyi nthawi zambiri imakhala kristalo, monga Nd:YAG (Neodymium-doped Yttrium Aluminium Garnet) kapena Ruby, yokhala ndi zinthu zapadziko lapansi zomwe zimathandizira kupanga kuwala kwa laser. Dope la kristalo ndi lomwe limakulitsa kuwala kuti apange kuwala kwa laser.

Wavelengths ndi Mapulogalamu:Ma laser a DPSS amatha kutulutsa mafunde osiyanasiyana, kutengera mtundu wa zinthu zomwe zimagwiritsidwa ntchito mu kristalo komanso kapangidwe ka laser. Mwachitsanzo, kasinthidwe wa laser wa DPSS amagwiritsa ntchito Nd:YAG ngati njira yopezera laser pa 1064 nm mu infuraredi sipekitiramu. Mtundu uwu wa laser chimagwiritsidwa ntchito mafakitale ntchito kudula, kuwotcherera, ndi kulemba zizindikiro zosiyanasiyana zipangizo.

Ubwino:Ma lasers a DPSS amadziwika chifukwa cha mtengo wawo wapamwamba kwambiri, magwiridwe antchito, komanso kudalirika. Ndiwopatsa mphamvu kuposa ma laser achikhalidwe olimba omwe amapopedwa ndi nyali ndipo amapereka moyo wautali wogwira ntchito chifukwa cha kulimba kwa ma laser a diode. Amathanso kupanga matabwa okhazikika komanso olondola a laser, omwe ndi ofunikira pakugwiritsa ntchito mwatsatanetsatane komanso molondola kwambiri.

Ntchito zazikulu za CW Diode Pumped Solid State Laser:

1.Kudula Diamondi Laser:

Laser ya G2-A imagwiritsa ntchito masinthidwe anthawi zonse kuwirikiza kawiri: mtengo wolowera infrared pa 1064 nm umasinthidwa kukhala mafunde obiriwira a 532-nm pamene ukudutsa mulu wosagwirizana. Njirayi, yomwe imadziwika kuti kuwirikiza kawiri kapena kubadwa kwachiwiri kwa harmonic (SHG), ndi njira yodziwika bwino yopangira kuwala pamafunde amfupi.

Mwa kuwirikiza kawiri kuchuluka kwa kuwala kochokera ku neodymium- kapena ytterbium-based 1064-nm laser, laser yathu ya G2-A imatha kutulutsa kuwala kobiriwira pa 532 nm. Njirayi ndiyofunikira popanga ma laser obiriwira, omwe amagwiritsidwa ntchito kwambiri pamagwiritsidwe kuyambira ma laser pointer kupita ku zida zapamwamba zasayansi ndi mafakitale, komanso kukhala otchuka kudera la Laser Diamond Cutting Area.

2. Kukonza Zinthu:

 Ma lasers amenewa amagwiritsidwa ntchito kwambiri pokonza zinthu monga kudula, kuwotcherera, ndi kubowola zitsulo ndi zipangizo zina. Kulondola kwawo kwapamwamba kumawapangitsa kukhala abwino kwa mapangidwe ndi masinthidwe ovuta, makamaka m'mafakitale amagalimoto, azamlengalenga, ndi zamagetsi.

3. Ntchito Zachipatala:

Pazachipatala, ma laser a CW DPSS amagwiritsidwa ntchito pa maopaleshoni omwe amafunikira kulondola kwambiri, monga maopaleshoni amaso (monga LASIK yowongolera masomphenya) ndi njira zosiyanasiyana zamano. Kuthekera kwawo kulunjika bwino minofu kumawapangitsa kukhala ofunikira m'maopaleshoni ochepa kwambiri.

4. Kafukufuku wa Sayansi:

Ma lasers awa amagwiritsidwa ntchito m'njira zosiyanasiyana zasayansi, kuphatikiza spectroscopy, particle image velocimetry (yogwiritsidwa ntchito mu mphamvu yamadzimadzi), ndi ma laser scanning microscopy. Kutulutsa kwawo kokhazikika ndikofunikira pamiyeso yolondola ndi kuwonera mu kafukufuku.

5. Matelefoni:

Pankhani yolumikizirana, ma DPSS lasers amagwiritsidwa ntchito munjira zoyankhulirana za fiber optic chifukwa chotha kupanga mtengo wokhazikika komanso wokhazikika, womwe ndi wofunikira potumiza deta mtunda wautali kudzera pa ulusi wamaso.

6. Laser chosema ndi chizindikiro:

Kulondola komanso kuchita bwino kwa ma lasers a CW DPSS amawapangitsa kukhala oyenera kuzokota ndikuyika chizindikiro pazinthu zosiyanasiyana, kuphatikiza zitsulo, mapulasitiki, ndi zoumba. Nthawi zambiri amagwiritsidwa ntchito ngati barcoding, ma serial manambala, komanso zinthu zopangira munthu payekha.

7. Chitetezo ndi Chitetezo:

Ma lasers awa amapeza ntchito zodzitchinjiriza pakusankhidwa kwa chandamale, kupeza mitundu yosiyanasiyana, komanso kuwunikira kwa infrared. Kudalirika kwawo komanso kulondola kwawo ndikofunikira m'malo okwera kwambiri.

8. Kupanga Ma Semiconductor:

M'makampani a semiconductor, ma laser a CW DPSS amagwiritsidwa ntchito ngati lithography, annealing, ndi kuyang'anira zowotcha za semiconductor. Kulondola kwa laser ndikofunikira pakupanga tinthu tating'onoting'ono pa tchipisi ta semiconductor.

9. Zosangalatsa ndi Zowonetsera:

Amagwiritsidwanso ntchito m'makampani azosangalatsa ngati mawonetsero opepuka komanso zowonera, pomwe kuthekera kwawo kutulutsa kuwala kowala komanso kokhazikika kumakhala kopindulitsa.

10. Biotechnology:

Mu biotechnology, ma lasers amagwiritsidwa ntchito ngati kutsatizana kwa DNA ndi kusanja ma cell, pomwe kulondola kwawo komanso kuwongolera mphamvu zawo ndikofunikira.

11. Metrology:

Kuti muyezedwe molondola komanso mulingo waumisiri ndi zomangamanga, ma laser a CW DPSS amapereka kulondola kofunikira pa ntchito monga kusanja, kuyanjanitsa, ndi mbiri.
