Kev faib tawm ntawm lasers
Raws li cov tub ntxhais tseem ceeb ntawm txhua daim ntawv thov cov khoom lag luam laser, lasers yog qhov tseem ceeb tshaj plaws ntawm txhua daim ntawv thov laser cov khoom lag luam.Thiab nws muaj ntau hom lasers. Tom ntej no, kev faib tawm ntawm cov khoom siv laser ua haujlwm, kev kub siab rau hom, hom kev ua haujlwm thiab cov khoom siv yoj yoj ntev yuav tswvcuab.
Raws li kev faib tawm ntawm cov khoom siv ua haujlwm, txhua lub lasers tuaj yeem muab faib ua cov pawg hauv qab no:
Cov khoom (siv lead ua thiab iav) laser:
Cov ua hauj lwm tshuaj siv los ntawm xws li lasers yog ua los ntawm kev ntxiv lub hlau ions uas tsim lub tsa tawg mus rau hauv lub crystalline los yog iav matrix.
Roj laser:
Lawv cov khoom siv ua haujlwm tau txais yuav los ntawm cov roj, thiab raws li cov roj av tsim los ntawm cov txiaj ntsig zoo ntawm qhov sib txawv ntawm kev ua haujlwm ntawm cov lus, thiab ntxiv faib ua cov roj cua atomic laser, ion roj lasers, molecular gas laser thiab excimer laser gas. , thiab lwm yam.;
Kua laser:
Tej laser ua hauj lwm txais yuav los ntawm cov ntaub ntawv uas tsuas yog muaj xws li ob hom, ib hom yog organic fluorescent cov xim tov, lwm yam yog inorganic tebchaw uas muaj tsawg lub ntiaj teb hlau ions nyob rau hauv cov tshuaj, uas plays ib tug luag hauj lwm ntawm kev ua hauj lwm particle hlau ions (Nd), thaum inorganic tebchaw kua (xws li SeOCl) plays ib tug luag hauj lwm ntawm lub hauv paus;
Semiconductor lasers:
Hom laser no yog cov khoom siv hluav taws xob semiconductor ua lub luag haujlwm ua cov khoom tsim tawm los ntawm kev ua kom muaj pa tawm ntawm hluav taws xob, txoj hauv paus ntawm uas yog los ntawm qee yam kev kub siab (hluav taws xob txhaj, twj tso lub teeb lossis lub zog hluav taws xob nqaj txhaj), nruab nrab ntawm cov kis ntawm cov khoom siv hluav taws xob lossis ntawm band thiab impurity qib, los ntawm kev txhawb nqa cov cab kuj thiab qhov sib npaug ntawm cov pejxeem inversion, lub luag haujlwm ntawm lub teeb yog tsim los ntawm kev ua kom tawm ntawm hluav taws xob;
Dawb electron laser:
Qhov no yog qhov tshwj xeeb ntawm hom tshiab ntawm laser, cov khoom ua haujlwm rau kev hloov pauv txhua ntu hauv qhov chaw ntawm qhov kev kub ceev txav hauv qhov chaw sib nqus ntsuas hluav taws xob tsis muaj hluav taws xob, ntev li ntev tau qhov kev hloov pauv ntawm cov teeb hluav taws xob dawb hluav taws xob tuaj yeem tsim kev sib pauv hloov hluav taws xob hluav taws xob, hauv txoj ntsiab cai, qhov sib haum xim hluav taws xob tuaj yeem hloov los ntawm xoo hluav taws xob hluav taws xob mus rau qhov chaw microwave, yog li nws yog qhov kev cia siab heev.
Raws li qhov sib txawv wavelength ntawm cov zis band, cov lasers sib txawv tuaj yeem muab cais raws li cov hauv qab no.
Laser infrared deb:
Cov nplaim hluav taws xob kis tau nyob nruab nrab ntawm 25 txog 1000 microns, thiab cov laser tso tawm qee cov pa roj molecular thiab lub tshuab hluav taws xob dawb lasers poob rau hauv thaj av no.
Nruab nrab infrared laser:
Cov cuab yeej siv laser nrog laser wavelength hauv nruab nrab infrared cheeb tsam (2.5 ~ 25 micron) yog sawv cev los ntawm lub tshuab pa roj carbon monoxide CO (10.6 micron) thiab CO cov roj molecular laser (5 ~ 6 micron).
Ze ntawm infrared laser:
Xa mus rau cov zis laser wavelength ze rau hauv cheeb tsam infrared (0.75 ~ 2.5 microns) ntawm cov khoom siv laser, cov neeg sawv cev rau neodymium doped khoom lub xeev laser (1.06 microns), CaAs semiconductor diode laser (li 0.8 micron) thiab qee cov roj laser, thiab lwm yam.
Pom laser:
Hais txog qhov tso tawm laser wavelength hauv thaj chaw pom (4000 ~ 7000 lossis 0.4 ~ 0.7 microns) ntawm cov khoom siv laser, cov sawv cev rau lub ruby laser (6943), nws-ne laser (6328), argon ion laser (4880, 5145) , krypton ion laser (4762, 5208, 5682, 6471), thiab qee qhov txiav txim siab zas xim laser, thiab lwm yam.
Nyob ze uv laser:
Cov khoom tso tawm laser wavelength ntau ntawm qhov ze ntawm ultraviolet spectral ntau (2000 ~ 4000), cov neeg sawv cev rau cov tshuaj molecular nitrogen (3371) ntawm xenon fluoride (XeF excimer laser (3511, 3531), krypton fluoride (KrF excimer laser (2490), thiab qee qhov ntawm cov tunable zas zas laser, thiab lwm yam
Lub tshuab nqus tsev ultraviolet laser; Lub tso zis laser wavelength ntau yog nyob rau hauv lub tshuab nqus tsev ultraviolet spectral cheeb tsam (50 ~ 2000 angers) thiab lub (H) molecular laser (H) molecular laser (1644 ~ 1098 et), xenon (Xe) excimer laser (1730 et), etc.
Xoo hluav taws xob laser:
Cov khoom tso tawm nthwv dej yog nyob hauv X-ray cheeb tsam spectrum (0.01 ~ 50 ceg). Tam sim no, mos xoo hluav taws xob tau tsim tau zoo, tab sis nws tseem nyob hauv kev tshawb nrhiav theem.
