Passive Q-switch modulators of plastic dye sheets ( Kodak 9850 cellulose acetate dye sheets), lithium fluoride crystals containing F 2 -color center ( LiF: F 2 -), chromium doped yttrium aluminum garnet crystals ( Cr 4+ :YAG), ionic color filter glass ( Schott RG1000 color filter glass) and the single crystal semiconductor wafers ( GaAs, Fe doped InP, Zn doped InP, S doped InP, etc.) have been investigated in our research. Especially in use those of the single crystal semiconductor wafer saturable absorbers, give us idea of developing the semiconductor substrate microchip lasers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
