Laser n'ozuzu nwere akụkụ atọ
(1) Laser na-arụ ọrụ usoro
Ọgbọ nke laser ga-ahọrọ usoro ọrụ kwesịrị ekwesị, nke nwere ike ịbụ gas, mmiri mmiri, siri ike ma ọ bụ semiconductor.N'ụdị usoro a, ntụgharị nke ọnụ ọgụgụ nke irighiri ihe nwere ike imezu, nke bụ ọnọdụ dị mkpa iji nweta laser.N'ụzọ doro anya, ịdị adị nke metastable ike larịị bụ nnọọ uru na mmezu nke ọnụ ọgụgụ inversion.Ka ọ dị ugbu a, enwere ụdị mgbasa ozi na-arụ ọrụ ihe fọrọ nke nta ka ọ bụrụ 1000, nke nwere ike imepụta ogologo ogologo ogologo laser dị iche iche site na VUV ruo infrared dị anya.
(2) Isi mmalite na-akpali akpali
Iji mee ka ntụgharị nke ọnụ ọgụgụ nke akụkụ ahụ pụta ìhè na usoro ọrụ, ọ dị mkpa iji ụzọ ụfọdụ na-akpali akpali usoro atomiki iji mee ka ọnụ ọgụgụ nke ihe dị elu dị elu.N'ozuzu, enwere ike iji mwepu gas kpalie atom dielectric site na electrons nwere ike kinetic, nke a na-akpọ mkpali eletrik;pulse light source nwekwara ike iji irradiate arụ ọrụ usoro, nke a na-akpọ anya excitation;Thermal excitation, chemical excitation, wdg A na-ahụ ụzọ dị iche iche mkpali dị ka mgbapụta ma ọ bụ mgbapụta.Iji nweta mmepụta laser na-aga n'ihu, ọ dị mkpa ịkwanye mmiri na-aga n'ihu iji mee ka ọnụ ọgụgụ nke ihe dị na elu dị elu karịa nke ahụ na ọkwa dị ala.
(3) oghere na-ada ụda
Na adabara na-arụ ọrụ ihe onwunwe na excitation isi iyi, inversion nke urughuru nọmba nwere ike na-aghọta, ma ike nke kpaliri radieshon bụ nnọọ adịghị ike, n'ihi ya, ọ na-apụghị etinyere na omume.Ya mere ndị mmadụ na-eche iji anya resonator na-amụbawanye.The na-akpọ ngwa anya resonator bụ n'ezie abụọ enyo na elu reflectivity arụnyere ihu na ihu na abụọ nsọtụ nke laser.Otu bụ ihe fọrọ nke nta ka ọ bụrụ nlebara anya zuru oke, nke ọzọ na-egosipụtakarị ma na-ebufe ntakịrị, nke mere na laser nwere ike ịpụta site na enyo.Ìhè ahụ na-atụgharị azụ na-arụ ọrụ na-aga n'ihu na-ebute radieshon na-akpali ọhụrụ, na ìhè na-abawanye.Ya mere, ọkụ na-atụgharị azụ na azụ na resonator, na-eme ka mmeghachi omume nke yinye, nke a na-eme ka ọ dịkwuo elu dị ka oké mmiri ozuzo, na-emepụta mmepụta laser siri ike site n'otu njedebe nke enyo na-atụgharị uche.
