Laser vuam khoom

Nws muaj qhov kho qhov muag oscillator thiab nruab nrab nruab nrab ntawm cov iav ntawm ob qho kawg ntawm cov kab noj hniav oscillator. Thaum qhov nruab nrab zoo siab rau lub xeev lub zog siab, nws pib tsim lub teeb nyob rau hauv-theem lub teeb thiab xav rov qab los ntawm daim iav ntawm ob qho kawg, tsim cov nyhuv photoelectric cascade, amplifying lub teeb nthwv dej, thiab tau txais lub zog txaus los pib emitting. lasers.
Laser kuj tuaj yeem piav qhia raws li cov cuab yeej siv los hloov lub zog xws li hluav taws xob, hluav taws xob, hluav taws xob, hluav taws xob, hluav taws xob, lub zog hluav taws xob lossis hluav taws xob nuclear rau hauv cov hluav taws xob hluav taws xob hluav taws xob ntawm qee qhov tshwj xeeb optical frequencies (ultraviolet light, pom lub teeb lossis infrared teeb). Daim ntawv hloov dua siab tshiab yog ib qho yooj yim rau ua nyob rau hauv tej yam khoom, kua los yog gaseous xov xwm. Thaum cov xov xwm no zoo siab rau hauv atomic lossis molecular daim ntawv, lawv tsim ib lub teeb ntawm lub teeb nrog yuav luag tib theem thiab ze li ntawm ib lub wavelength - laser. Vim yog nyob rau hauv-theem thiab ib lub wavelength, qhov sib txawv lub kaum sab xis yog heev me me, thiab qhov kev ncua deb uas yuav kis tau ua ntej yuav muaj siab concentrated los muab lub zog xws li vuam, txiav thiab kev kho cua sov yog ntev heev.
