Yb:YAG–1030 nm Laser Crystal Promising Laser-active Material
Incazelo Yomkhiqizo
Ikristalu ye-Yb:YAG kulindeleke ukuthi ithathele indawo yekristalu ye-Nd:YAG kumalaser ampontshelwa nge-diode enamandla amakhulu nezinye izinhlelo zokusebenza ezingaba khona.
I-Yb:YAG ibonisa isithembiso esihle njengempahla yelaser enamandla amakhulu. Izicelo eziningana ziyathuthukiswa emkhakheni wama-lasers wezimboni, njengokusika insimbi nokushisela. Njengoba ikhwalithi ephezulu ye-Yb:YAG isitholakala, izinkambu ezengeziwe nezinhlelo zokusebenza ziyahlolwa.
Izinzuzo Ze-Yb:YAG Crystal
● Ukushisisa okuphansi kakhulu, ngaphansi kuka-11%
● Ukusebenza kahle kwe-slope ephezulu kakhulu
● Amabhendi okumunca abanzi, angaba ngu-8nm@940nm
● Akukho ukumuncwa kwesimo esijabulile noma ukuguqulwa okuphezulu
● Impontshwa kalula ngama-InGaAs diode angu-940nm (noma 970nm)
● High conductivity ezishisayo namandla amakhulu mechanical
● Ikhwalithi ephezulu yokubona
Izinhlelo zokusebenza
Ngebhendi yephampu ebanzi kanye nesigaba esiphambanayo sokukhishwa okuhle kakhulu i-Yb:YAG iyikristalu efanelekile yokumpompa i-diode.
