Cr4+: YAG – Qalab ku habboon Q- beddelashada
Sharaxaada Alaabta
Crystal Passive Q-switch ayaa loo door bidaa fududaynta wax soo saarka iyo hawlgalka, kharash yar, iyo hoos u dhigida cabbirka nidaamka iyo miisaanka.
Cr4+: YAG kiimikaad ahaan waa u xasiloon tahay, UV adkaysi u leh waana waaraya. Cr4+: YAG waxay ku shaqayn doontaa heerkul balaadhan iyo xaalado kala duwan.
Wanaajinta kulaylka wanaagsan ee Cr4 +: YAG waxay si fiican ugu habboon tahay codsiyada celceliska sare.
Natiijooyin aad u wanaagsan ayaa la soo bandhigay iyadoo la adeegsanayo Cr4+: YAG sidii Q-bedel aan fiicneyn oo loogu talagalay Nd: YAG lasers. Faleefoonka qoyaanka ayaa lagu qiyaasay inuu ahaa ku dhawaad 0.5 J/cm2. Waqtiga soo kabashada gaabiska ah ee 8.5µs, marka la barbar dhigo dheeha, ayaa faa'iido u leh xakamaynta qaabka qufulka.
Cabirka garaaca garaaca Q-beddelay ee 7 ilaa 70 ns iyo celceliska celceliska ilaa 30 Hz ayaa la gaadhay. Tijaabooyinka Burburka Laser-ka waxay muujiyeen AR dahaarka leh Cr4+: YAG Q-switches dadban ayaa dhaaftay 500 MW/cm2.
Tayada indhaha iyo isku midka ah ee Cr4+: YAG waa mid aad u fiican. Si loo yareeyo luminta galinta, crystals waa dahaarka AR. Cr4+: YAG crystals waxaa la bixiyaa dhexroorka caadiga ah, iyo cufnaanta indhaha iyo dhererka kala duwan si ay u waafaqaan waxyaabahaaga.
Waxa kale oo loo isticmaali karaa in lagu xidho Nd:YAG iyo Nd,Ce:YAG,xajmiga caadiga ah sida D5*(85+5)
Faa'iidooyinka Cr4+: YAG
● Degganaanshiyo kiimikaad oo sarreeya iyo isku halaynta
● In ay fududahay in lagu qalo
● Heerka burburka sare (> 500MW/cm2)
● Sida awood sare, xaalad adag iyo is haysta Q-Switch
● Wakhtiga cimriga dheer iyo kulaylka wanaagsan
