Chinhu chikuruhunhu hwema lasers

Chizvarwa chelasersDzidziso ye "mwaranzi inongoerekana yavapo uye inosimudzirwa" yakataurwa naEinstein muna 1916 ndiyo hwaro hwemazuva anosisitimu yelaserKudyidzana kuripo pakati pemaphoton nemaatomu kunogona kukonzera mhando nhatu dzekuchinja: kunyudzwa kunokurudzirwa, kubuda kwemasero, uye kubuda kwemasero.

Hunhu hukuru hwema lasers ndeinotevera:

1. Kutungamira kwakanaka: Sezvo mwenje wechiedza uri kupararira pamwe chete nechikamu che resonant cavity chete ndiwo unogona kuumba oscillation uye continuous amplification, laser output kubva ku laser ine Angle diki yekusiyana uye kutungamira kwakanaka, zvichiita kuti ive sosi yechiedza chakafanana.

2. Kupenya kwakanyanya: Nekuda kwekutungamira kwayo kwakanaka, simba relaser rakanyanya kuzara muchadenga, zvichiita kuti rive nesimba guru kwazvo. Kupenya kwezuva kwakajairika kunenge 100W/cm². Kupenya kwechiedza chelaser yehelium-neon ine simba remamilliwatts akati wandei kunogona kukwira kane mazana kupfuura kwezuva. Laser inoshanda mupulsed

chiedza chinogona kuva chakakwirira ka107 kusvika 1014 kupfuura chiedza chezuva.

3. Kupenya kwechiedza chimwe chete: Nekuda kwekuti maphotoni anogadzirwa nemwaranzi inomutswa ane frequency yakafanana uye anoganhurirwa ne resonant cavity, chiedza chewavelength chaiyo chete ndicho chinogona kutenderera uye kubuda. Saka, lasers dzine kupenya kwechiedza chimwe chete kwakanaka.

4. Kubatana kwakanaka: Chiedza chakajairika chinogadzirwa nemwaranzi inongoerekana yavapo chiedza chisina kurongeka, nepo hunhu hwechiedza chinobudiswa nemwaranzi inosimudzirwa hunoita kuti lasers ive nekubatana kwakanaka. Hunhu hukuru uhu huna hunopa matekiniki matsva ekuongorora uye matekiniki ekuziva mifananidzo yemishonga nebiology.

Njodzi dze lasers uye matanho ekuchengetedza

Kukuvadzwa kunogona kukonzerwa nemalaser mumuviri wemunhu kunogona kukamurwa muzvikamu zviviri. Rudzi rumwe kukuvara kwakananga, kureva kuti, mwaranzi yechiedza yemalaser inodarika chiyero chekuchengetedza inokonzera kukuvara kumaziso, ganda, sisitimu yetsinga uye nhengo dzemukati. Rumwe rudzi kukuvara kusina kunanga kunokonzerwa nezvinhu zvakaita semagetsi ane simba rakawanda, ruzha, mafiriji anodziya uye masosi emagetsi. Saka, matanho ekuchengetedza anoenderana anofanira kutorwa: kutarisa nekutarisira sisitimu yelaser nenzvimbo yekushanda, pamwe nekudzivirira munhu.
