Lembetsani ku Social Media Yathu Kuti Mutumize Posachedwa
Pazinthu zamakono zamakono zamakono, ma lasers amapanga niche yapadera, yosiyanitsidwa ndi kulondola kosayerekezeka, kusinthasintha, ndi kufalikira kwa ntchito yawo. M'derali, laser yobiriwira ya 525nm, makamaka yolumikizidwa ndi ulusi, imadziwika bwino chifukwa cha mawonekedwe ake apadera komanso magwiridwe antchito osiyanasiyana m'malo oyambira kuchokera ku njira zosakhala zakupha mpaka pazachipatala chaukadaulo. Kufufuza uku kukufuna kutulutsa mitundu yosiyanasiyana ya525nm obiriwira lasers, ndikuwunikira udindo wawo wofunikira m'magawo osiyanasiyana monga okhudza malamulo, zaumoyo, chitetezo, ndi zosangalatsa zakunja. Kuphatikiza apo, nkhani iyi ifotokoza za kusiyana pakati pa 525nm ndi 532nm green lasers, kutsindika madera awo olamulira.
532nm Green Laser Mapulogalamu
Ma lasers obiriwira a 532nm amakondweretsedwa chifukwa cha kuwala kwawo, kobiriwira kobiriwira, kogwirizana kwambiri ndi kukhudzika kwa nsonga ya maso a munthu pansi pa kuyatsa kwanthawi zonse, kuwapangitsa kukhala ofunikira m'magawo angapo. M'malo ofufuza asayansi, ma lasers awa ndi ofunikira kwambiri pa microscopy ya fluorescence, kuthandizira kusangalatsa kwamitundu yambiri ya fluorophores, komanso ma spectroscopy kuti muwunike mwatsatanetsatane zolemba zakuthupi. Othandizira azachipatala amagwiritsa ntchito ma lasers awa munjira monga ophthalmologic laser photocoagulation pochiza zotupa za retina, komanso kugwiritsa ntchito dermatological cholinga chochotsa zotupa zapakhungu. Ntchito zamafakitale za 532nm lasers zikuwonekera mu ntchito zomwe zimafuna mawonekedwe apamwamba monga kujambula kwa laser, kudula, ndi kuyanjanitsa. Kuphatikiza apo, kukopa kwawo pamagetsi ogula pamagetsi a laser, komanso m'makampani azosangalatsa akuwonetsa kuwala, kumatsimikizira kugwiritsidwa ntchito kwawo kwakukulu, mwachilolezo cha matabwa awo obiriwira.
Kodi Dpss Laser imapanga bwanji laser yobiriwira ya 532nm?
Kupanga kwa 532nm green laser kuwala kudzera pa DPSS (Diode-Pumped Solid State) ukadaulo wa laser kumaphatikizapo njira yovuta. Poyamba, kuwala kwa infrared pa 1064 nm kumapangidwa pogwiritsa ntchito neodymium-doped crystal yomwe imapopedwa ndi Diode Laser. Kuwala kumeneku kumawongoleredwa kudzera mu kristalo wopanda mzere, womwe umachulukitsa pafupipafupi, ndikuchepetsa kutalika kwake, motero kutulutsa kuwala kobiriwira kobiriwira pa 532 nm.

525nm Green Laser Mawonekedwe Ogwiritsa Ntchito
Kulowera mumtundu wa 525nm wobiriwira wa laser, makamaka mitundu yake yophatikizika ndi ulusi, kumawonetsa kufunikira kwake pakupanga zida zamagetsi zamagetsi. Zida zosapha izi zimapangidwira kuti zisokoneze kapena kusokoneza malingaliro a chandamale popanda kuwononga kosatha, zomwe zimapangitsa kuti zikhale chisankho chabwino kwambiri pazachitetezo chankhondo ndi malamulo. Amagwiritsidwa ntchito makamaka poyang'anira kuchuluka kwa anthu, chitetezo cha malo ochezera, komanso kuletsa ziwopsezo zomwe zingachitike, zida za laser zimachepetsa chiwopsezo cha kuvulala kwakanthawi. Kuphatikiza apo, kugwiritsa ntchito kwawo pamakina odana ndi magalimoto kumawonetsa kuthekera kwawo kuyimitsa kapena kuwongolera magalimoto mosatekeseka pochititsa khungu kwakanthawi, kuwonetsetsa chitetezo panthawi yothamangitsa kapena poyang'ana.
Kugwiritsa ntchito ma laser obiriwira a 525nm kumapitilira kugwiritsa ntchito mwanzeru kuphatikiza kuwunikira komanso kukulitsa mawonekedwe. Kusankhidwa kwa kutalika kwa mawonekedwe a 525nm, pafupi ndi kukhudzika kwamaso kwa munthu pansi pa mikhalidwe yambiri yowunikira, kumapereka mawonekedwe apadera. Izi zimapangitsa kuti laser yobiriwira ya 525nm ikhale chida chamtengo wapatali chowunikira, makamaka pakufufuza ndi kupulumutsa komwe kumawoneka ndikofunikira. Kuphatikiza apo, mawonekedwe awo apamwamba amawapangitsa kukhala abwino ku zochitika zakunja monga kukwera maulendo, kumanga msasa, ndi kusaina kwadzidzidzi, kukhala ngati nyali yamphamvu pakagwa zovuta.
Inzochitika zachitetezo, kulondola komanso kuwoneka kwa ma laser obiriwira a 525nm amathandizidwa kuti atchule chandamale ndikupeza mitundu yosiyanasiyana, kuthandizira kuyeza kolondola kwa mtunda wopita komwe mukufuna komanso kutsogolera zida zankhondo, potero kumawonjezera mphamvu yankhondo. Amagwiranso ntchito yofunika kwambiri pakuwunika komanso kuzindikira, makamaka panthawi yantchito yausiku, powunikira ndikuyika chizindikiro pamakamera owunika komanso zida zowonera usiku.
Thezachipatalaamapindulanso ndi kupita patsogolo kwaukadaulo wa 525nm green laser, makamaka mu retinal photocoagulation, kutsimikizira kuthekera kwawo kosintha mbali zosiyanasiyana za chithandizo chamankhwala. Kuphatikiza apo, kupanga ma laser amphamvu kwambiri pamafakitale ndi sayansi kumawonetsa kusinthasintha komanso kuthekera kwa ma laser obiriwira, ndikupita patsogolo monga AlInGaN-based green laser diode kukwaniritsa zotsatira za 1W pa 525nm, kulengeza mwayi watsopano wofufuza ndi chitukuko.
Malingaliro owongolera ndi ma protocol achitetezo omwe amalamulira kagwiritsidwe ntchito ka ma laser obiriwira a 525nm ndiofunikira, makamaka akagwiritsidwa ntchito poletsa kupha anthu komanso chitetezo cha anthu, kuwonetsetsa kuti mapindu aukadaulo wa laser wobiriwira akugwiritsidwa ntchito moyenera, kuchepetsa ziwopsezo zobwera chifukwa chogwiritsa ntchito molakwika kapena kuwonekera mopitilira muyeso.
Pomaliza, laser yobiriwira ya 525nm imatuluka ngati chowunikira chaukadaulo, ndikugwiritsa ntchito kwake kutengera chitetezo, chithandizo chamankhwala, kafukufuku wasayansi, ndi kupitilira apo. Kusinthasintha kwake komanso kuchita bwino kwake, komwe kumachokera ku chilengedwe cha kutalika kwa mawonekedwe obiriwira, kumatanthawuza kuthekera kwa laser kupititsa patsogolo kupita patsogolo ndi zatsopano m'magawo ambiri.
