Key e ji mara laser nweta ọkara

Kedu ihe bụ isi njirimara nke mgbasa ozi nweta laser?

Laser nweta ọkara, nke a makwaara dị ka ihe na-arụ ọrụ laser, na-ezo aka na usoro ihe eji eme ihe iji nweta ngbanwe nke ọnụ ọgụgụ mmadụ ma mepụta radieshon kpaliri iji nweta mmụba ọkụ. Ọ bụ isi akụrụngwa nke laser, na-ebu ọnụ ọgụgụ dị ukwuu nke atọm ma ọ bụ ụmụ irighiri ihe, ndị a atọm ma ọ bụ ụmụ irighiri ihe n'okpuru excitation nke mpụga ike, nwere ike mgbanwe na obi ụtọ ala, na site obi ụtọ radieshon tọhapụrụ photons, si otú a na-akpụ aọkụ laser. The laser uru ọkara nwere ike ịbụ a siri ike, mmiri mmiri, gas ma ọ bụ semiconductor ihe.
N'ime laser steeti siri ike, mgbasa ozi ndị a na-ejikarị enweta bụ kristal doped na ion ụwa na-adịghị ahụkebe ma ọ bụ ion ngbanwe metal, dị ka Nd: YAG kristal, Nd: YVO4 kristal, wdg N'ime lasers mmiri mmiri, a na-ejikarị akwa organic eme ihe dị ka mgbasa ozi. Laser gas na-eji gas dị ka ihe na-enweta ihe, dị ka carbon dioxide gas na carbon dioxide lasers, na helium na neon gas na helium-neon lasers.Semiconductor lasersjiri ihe semiconductor dị ka ihe na-enweta uru, dị ka gallium arsenide (GaAs).
Isi njirimara nke usoro uru laser gụnyere:
Ọdịdị ọkwa ume: Atọm ma ọ bụ ụmụ irighiri ihe ndị dị n'ọkwa uru kwesịrị inwe nhazi ọkwa ume kwesịrị ekwesị iji nweta ngbanwe nke ndị mmadụ n'okpuru mkpali nke ike mpụga. Nke a na-apụtakarị na ọdịiche ike dị n'etiti ọkwa ike dị elu na nke dị ala kwesịrị dakọtara na ike foton nke otu ogologo ogologo.

Njirimara mgbanwe: Atọm ma ọ bụ ụmụ irighiri ihe dị na steeti ndị nwere obi ụtọ kwesịrị inwe ihe ngbanwe kwụsiri ike iji wepụta foton na-emekọrịta ihe n'oge radieshon na-atọ ụtọ. Nke a na-achọ ka onye na-enweta uru nwere oke arụmọrụ quantum na mfu dị ala.
Thermal kwụsie ike na n'ibu ike: N'ime ngwa ngwa, uru ọkara kwesịrị iguzogide elu ike mgbapụta ọkụ na laser mmepụta, n'ihi ya, ọ kwesịrị inwe ezi thermal kwụsie ike na n'ibu ike.
Ogo anya: Ọdịdị anya nke ihe na-enweta uru dị oke mkpa maka ịrụ ọrụ nke laser. Ọ kwesịrị inwe oke ọkụ na-ebufe na nkwụsịtụ dị ala iji hụ na ịdị mma na nkwụsi ike nke eriri laser. The oke nke laser uru ọkara dabere na ngwa chọrọ nkelaser, Ogologo ogologo ọrụ, ike mmepụta na ihe ndị ọzọ. Site n'ịkwalite ihe na nhazi nke ihe na-enweta uru, arụmọrụ na arụmọrụ nke laser nwere ike ime ka ọ dịkwuo mma.
