Yb CaF2 Laser Muaj Zauv

Vim yog lub toughness thiab cov txheej txheem saj zawg zog thiab pheej yig, CaF 2 tau siv ntau yam khoom siv rau substrate rau laser muaju. Raws li kev ua kom nrov muaj zog, Yb 3+ kuj tso cai rau peb lub tswv yim laser, uas ua rau tsis tshua muaj cov ntus cov qaub thiab ua rau lub neej tsis tshua ntev dua.

Kev piav qhia

Vim yog lub toughness thiab cov txheej txheem saj zawg zog thiab pheej yig, CaF 2 tau siv ntau yam khoom siv rau substrate rau laser muaju. Raws li kev ua kom nrov muaj zog, Yb 3+ kuj tso cai rau peb lub tswv yim laser, uas ua rau tsis tshua muaj cov ntus cov qaub thiab ua rau lub neej tsis tshua ntev dua. Yb 3+ : CaF 2 kuj tseem tuaj yeem muab cov khoom kho qhov muag siab siab thiab siab tso zis ntau vim cov thermal load txo. Tsis ntev los no, ytterbium-doped alkaline-av fluoride feem ntau yog siv hauv diode-pumped femtosecond laser thiab amplifiers. Cov kab mob Alkaline-earth fluorides uas yooj yim zus tau los ntawm kev siv tus txheej txheem ntawm Czochralski los yog Bridgman cov txheej txheem qhia tau hais tias muaj peev xwm ua tau zoo tshaj plaws nyob rau hauv ntau qhov kev sib kis, muaj kev puas tsuaj siab thiab tsis sib haum xeeb.
