Laser Crystal-Yb: YAG

1 Qhia

Yb: YAG Crystals possesses ntau yam txaus nyiam cov laser nrog rau kev ua kom muaj nuj nqis quantum, tsis muaj kev txaus siab lub xeev thiab tsis hloov siab, kev ua haujlwm ntev hauv qib laser, loj haum dav, dav emission, zoo kho qhov muag, thermal thiab mechanical zog, yog li ntawd nws yog pom tau tias yog qhov peev xwm ua tau zoo tshaj plaws rau kev ua haujlwm tau zoo, muaj peev xwm siv zog ua kom muaj zog-lub xeev lasers.
