CW DPSS laser yog dab tsi? Definition Break-down

Nruam Wave (CW):Qhov no yog hais txog kev ua haujlwm ntawm lub laser. Nyob rau hauv CW hom, lub laser emits ib tug khov kho, tas li beam ntawm lub teeb, as opposed to pulsed lasers uas emit lub teeb nyob rau hauv tawg. CW lasers yog siv thaum lub teeb pom kev tas li, ruaj khov, xws li hauv kev txiav, vuam, lossis daim ntawv sau npe.

Diode Pumping:Nyob rau hauv diode-pumped lasers, lub zog siv los excite lub laser nruab nrab yog muab los ntawm semiconductor laser diodes. Cov diodes emit lub teeb uas yog absorbed los ntawm lub laser nruab nrab, zoo siab rau cov atoms nyob rau hauv nws thiab cia lawv emit coherent lub teeb. Diode twj siv tau ntau dua thiab txhim khu kev qha piv rau cov txheej txheem qub ntawm kev siv, xws li flashlamps, thiab tso cai rau ntau qhov kev cog lus thiab ruaj khov laser.

Solid-State Laser:Lo lus "solid-state" yog hais txog hom nce nruab nrab siv hauv laser. Tsis zoo li roj los yog kua lasers, cov khoom siv lub xeev lasers siv cov khoom siv los ua qhov nruab nrab. Qhov nruab nrab no feem ntau yog siv lead ua, zoo li Nd: YAG (Neodymium-doped Yttrium Aluminium Garnet) los yog Ruby, doped nrog lub ntiaj teb tsis tshua muaj cov ntsiab lus uas ua rau lub cim ntawm lub teeb laser. Lub doped siv lead ua yog dab tsi amplifies lub teeb los tsim lub laser beam.

Wavelengths thiab kev siv:DPSS lasers tuaj yeem tso tawm ntawm ntau lub wavelengths, nyob ntawm seb hom doping khoom siv hauv cov siv lead ua thiab qhov tsim ntawm lub laser. Piv txwv li, ib qho DPSS laser configuration siv Nd:YAG raws li qhov nce nruab nrab los tsim ib lub laser ntawm 1064 nm hauv infrared spectrum. Hom laser no yog siv dav hauv kev lag luam siv rau kev txiav, vuam, thiab kos ntau yam ntaub ntawv.

Qhov zoo:DPSS lasers paub txog lawv cov kab teeb pom kev zoo, kev ua haujlwm zoo, thiab kev ntseeg tau. Lawv muaj zog ntau dua li cov khoom siv hauv lub xeev cov lasers uas siv los ntawm flashlamps thiab muab lub neej ua haujlwm ntev dua vim kev ua haujlwm ntawm diode lasers. Lawv kuj muaj peev xwm ua tau zoo heev ruaj khov thiab meej laser beams, uas yog ib qho tseem ceeb rau cov ncauj lus kom ntxaws thiab high-precision daim ntaub ntawv.
