Chii chinonzi Laser
Laser chiedza chinokwidziridzwa nekutora simba rinopenya.Laser radiation inogadzirwa nelaser sosi, uye yakakwirira-density simba rinofadza makristaro tsvimbo (solid-state lasers) kana yakakosha gasi musanganiswa. (gasi lasers) kugadzira laser mwaranzi.Iri simba rinopihwa muchimiro chechiedza (flash rambi kana diode laser) kana kubuda kwemagetsi (yakaenzana nemwenje wefluorescent).A crystal tsvimbo kana laser-activated gasi iri pakati pemagirazi maviri kuti igadzire laser resonant cavity kutungamira laser kune yakananga nzira uye kukwidziridza chiratidzo chemaziso nenzira iyi.Laser inopfuura kuburikidza negirazi rakajeka mune imwe chikamu uye rinoshandiswa kugadzirisa zvinhu.Nheyo dzeLaser Processing
Ma lasers ese ane zvinhu zvitatu zvinotevera: Pombi sosi Yakasimudzwa yepakati Resonant mhango Iyo pombi sosi inopa simba kubva kune yekunze kunobva kune laser.Iyo yekunakidzwa yepakati inowanikwa mukati me laser.Zvichienderana nekugadzirwa kweiyo laser chimiro, iyo laser medium inogona kunge iri gasi musanganiswa (CO2 laser), crystal tsvimbo (YAG yakasimba laser) kana girazi fiber. (fiber laser).Kana iyo laser yepakati ichipihwa simba kubva kune yekunze pombi sosi, inofara kuburitsa simba remwaranzi.Iyo inonakidza svikiro iri pakati pemagirazi maviri pamigumo yese yegomba resonant.Chimwe chezvionioni inzira imwe chete lenzi (hafu yegirazi).Iyo simba mwaranzi inogadzirwa ne excited medium inowedzerwa mune resonant cavity.Panguva imwecheteyo, pane imwe chete chaiyo Iyo radiation inogona kupfuura nenzira imwe-lens kuumba danda remwaranzi, inova laser.
Laser ine matatu makuru maitiro:Kufanana: Laser mwaranzi inongori imwe chete chaiyo wavelength yechiedza Kubatana: iyo yakafanana nhanho Parallelism: Chiyedza chiri mulaser beam chinofambirana zvakanyanya Iyo laser mwenje inofambirana zvakanyanya isati yapfuura nepakati inotarisa lens.Mukati meiyo yakatarisana nehurefu hweiyo laser beam, yakanyanya kusimba simba inogadzirwa, iyo inogona kushandiswa kunyungudutsa kana kuputika zvinhu.Mukuwedzera, kushandiswa kwezvinhu zvakakodzera optical elements (lenses) zvinogona kutungamirira uye kuratidza laser light, uye hapazovi nekurasikirwa kunyange kure kure.Iyo yekumisikidza sisitimu (laser pointer) kana galvanometer scanner inoshandiswa senharembozha.Sezvo danda relaser risingazofambiswe, ichi chishandiso chepasirese, chisina kupfeka.
