Cr4 +: YAG -Chinthu Chabwino Kwambiri Pakusintha kwa Passive Q
Mafotokozedwe Akatundu
Crystal Passive Q-switch imakondedwa kuti ikhale yosavuta kupanga ndikugwira ntchito, yotsika mtengo, komanso kuchepetsa kukula ndi kulemera kwa dongosolo.
Cr4 +: YAG ndi yokhazikika pamakina, imalimbana ndi UV ndipo ndiyokhazikika. Cr4 +: YAG idzagwira ntchito pamitundu yosiyanasiyana ya kutentha ndi mikhalidwe.
Kutentha kwabwino kwa Cr4 +: YAG ndikoyenera kugwiritsa ntchito mphamvu zambiri.
Zotsatira zabwino zawonetsedwa pogwiritsa ntchito Cr4+:YAG ngati Q-switch ya Nd:YAG lasers. Kuthamanga kwachulukidwe kunayezedwa kukhala pafupifupi 0.5 J/cm2. Nthawi yobwezeretsa pang'onopang'ono ya 8.5 µs, poyerekeza ndi utoto, ndiyothandiza poletsa kutseka kwa mode.
Q-switched pulsewidths ya 7 mpaka 70 ns ndi mitengo yobwerezabwereza mpaka 30 Hz yakwaniritsidwa. Mayeso a Laser Damage Threshold adawonetsa AR yokutidwa Cr4 +: YAG passive Q-switches idaposa 500 MW / cm2.
Ubwino wa kuwala ndi homogeneity ya Cr4 +: YAG ndiyabwino kwambiri. Kuti muchepetse kutayika koyika makhiristo amakutidwa ndi AR. Cr4 +: makhiristo a YAG amaperekedwa ndi mainchesi wokhazikika, komanso makulidwe osiyanasiyana owoneka bwino ndi kutalika kuti agwirizane ndi zomwe mukufuna.
Itha kugwiritsidwanso ntchito kugwirizana ndi Nd: YAG ndi Nd, Ce: YAG, kukula wamba monga D5 * (85 + 5)
Ubwino wa Cr4 +: YAG
● Kukhazikika kwa mankhwala ndi kudalirika
● Kukhala kosavuta kugwiritsa ntchito
● Kuwonongeka kwakukulu (> 500MW/cm2)
● Monga mphamvu yapamwamba, yolimba komanso yosakanikirana ndi Q-Switch
● Moyo wautali nthawi ndi madutsidwe wabwino matenthedwe
