1. CW lasers: Cov lasers emit laser teeb tsis tu ncua, es tsis nyob rau hauv pulses. Lawv feem ntau siv rau hauv cov ntawv thov uas yuav tsum muaj cov khoom siv laser ruaj khov, xws li laser txiav, vuam, thiab cov txheej txheem kho mob.
2. Solid-state lasers: Siv cov khoom siv hauv lub xeev tau txais xov xwm, xws li Nd:YAG lossis Ti: sapphire, lawv muaj peev xwm tsim tau lub zog hluav taws xob txuas ntxiv lossis lub teeb ci laser. Cov lasers no feem ntau siv hauv kev lag luam, kev kho mob, thiab kev siv tub rog.
3. Gas lasers: Siv roj los ua qhov nruab nrab nce, xws li helium-neon lasers (He-Ne) thiab carbon dioxide lasers (CO2). Lawv tuaj yeem tsim lub teeb laser ntawm qhov sib txawv wavelengths thiab tsim nyog rau kev ntsuas, kev kho mob, thiab kev ua lag luam.
4. Semiconductor lasers (tseem hu ua laser diodes): Ua los ntawm cov khoom siv semiconductor, lawv tuaj yeem hloov hluav taws xob zoo rau hauv lub teeb lub zog. Lawv feem ntau siv hauv kev sib txuas lus fiber ntau, laser tshuab luam ntawv, thiab qee yam khoom siv kho mob.
5. Dye lasers: Siv cov kua dyes raws li kev tshaj tawm, lawv tuaj yeem hloov kho los tsim lub teeb laser ntawm ntau lub wavelengths thiab tsim nyog rau kev tshawb fawb thiab qee cov txheej txheem kho mob.
6. Fiber laser: Siv cov fiber ntau optical doped nrog cov ntsiab lus tsis tshua muaj hauv ntiaj teb raws li qhov nruab nrab nce, nws tuaj yeem tsim cov khoom zoo txuas ntxiv lossis pulsed lasers, haum rau cov khoom siv, kev siv tub rog thiab kev kho mob.
7. Dawb electron laser: Siv cov kab hluav taws xob dawb es tsis txhob nce cov xov xwm los tsim cov lasers, nws tuaj yeem tsim cov lasers nrog ntau lub wavelength dav, haum rau kev tshawb fawb.
8. Excimer laser: Siv cov pa roj excimer los ua qhov nruab nrab los tsim cov lasers hauv ultraviolet band, nws feem ntau siv hauv micromachining, ophthalmic phais thiab lithography.
9. Chemical laser: Ua lasers los ntawm cov tshuaj tiv thaiv, feem ntau yog siv nyob rau hauv high-zog tso zis daim ntaub ntawv xws li cov tub rog tiv thaiv systems.
Txhua lub laser muaj nws daim ntawv thov tshwj xeeb, thiab xaiv lub laser txoj cai nyob ntawm qhov yuav tsum tau muaj cov yam ntxwv laser, xws li wavelength, lub zog, mem tes dav thiab coherence.
