CW lasers yog siv thaum xav tau lub teeb ci ntsa iab tas mus li, xws li hauv kev txiav, vuam, lossis kev kos duab.

Diode Pumping:Hauv cov lasers uas siv diode-pumped, lub zog uas siv los ua kom lub laser medium zoo siab yog muab los ntawm semiconductor laser diodes. Cov diodes no tso tawm lub teeb uas lub laser medium nqus tau, ua rau cov atoms hauv nws zoo siab thiab tso cai rau lawv tso tawm lub teeb sib xws. Diode pumping muaj txiaj ntsig zoo dua thiab txhim khu kev qha dua li cov txheej txheem pumping qub, xws li flashlamps, thiab tso cai rau cov qauv laser compact thiab ruaj khov dua.

Laser Khoom Siv-Lub Xeev:Lo lus "solid-state" txhais tau hais tias hom gain medium siv hauv laser. Tsis zoo li roj lossis kua lasers, solid-state lasers siv cov khoom khov ua cov khoom nruab nrab. Cov khoom nruab nrab no feem ntau yog siv lead ua, zoo li Nd:YAG (Neodymium-doped Yttrium Aluminium Garnet) lossis Ruby, doped nrog cov khoom tsis tshua muaj uas ua rau lub teeb laser tsim tau. Lub siv lead ua doped yog qhov ua kom lub teeb loj dua los tsim cov teeb laser.

Wavelengths thiab Daim Ntawv Thov:Cov laser DPSS tuaj yeem tso tawm ntawm ntau qhov wavelengths, nyob ntawm hom khoom siv doping siv rau hauv cov siv lead ua thiab kev tsim ntawm lub laser. Piv txwv li, ib qho kev teeb tsa laser DPSS siv Nd: YAG ua qhov nruab nrab kom tsim tau lub laser ntawm 1064 nm hauv lub spectrum infrared. Hom laser no siv dav hauv kev siv hauv kev lag luam rau kev txiav, vuam, thiab cim ntau yam khoom.

Cov txiaj ntsig:Cov laser DPSS paub txog lawv qhov zoo ntawm lub teeb ci, kev ua haujlwm zoo, thiab kev ntseeg siab. Lawv siv hluav taws xob ntau dua li cov laser solid-state uas siv los ntawm lub teeb ci thiab muaj lub neej ua haujlwm ntev dua vim yog lub zog ntawm cov diode lasers. Lawv kuj muaj peev xwm tsim cov teeb laser ruaj khov thiab meej, uas yog qhov tseem ceeb rau kev siv cov ntaub ntawv ntxaws ntxaws thiab kev ua haujlwm siab.
