Laser Crystal-Nd: YAG

1 Qhia

Neodymium doped Yttrium Aluminium Garnet (Nd: Y 3 Al 5 O 12 lossis Nd: YAG) siv lead ua, uas yog qhov zoo tshaj plaws ntawm cov khoom lag luam tsawg tsawg ntawm cov khoom lag luam uas tau ua los ntawm plaub qib laser lag luam uas tso cai rau cov ntsev qis thiab CW ua haujlwm. Nws yog qhov paub tshaj thiab dav siv los ntawm cov khoom siv hauv xeev uas tau txais los ntawm R & D, kev kho mob, kev lag luam thiab tub rog. Nws qhov tseem ceeb thiab pom tau zoo yog: kev siab hlob, kev sib tw tsawg, kev ua haujlwm siab, kev poob qis ntawm 1,064 μm, thiab kev kho siab zoo, kev thermal conductivity thiab thermal shock yam ntxwv, ruaj khov chemical thiab mechanical zog, uas ua Nd: YAG raws li feem ntau cov khoom tsim thiab coj mus muag rau ntau hom kev lag luam (CW, pulsed, Q-switched, hom xauv thiab kab noj hniav).
