Stimulated emission from Er³⁺ions in yttrium aluminum garnet crystals at λ = 2.94 μ

Structural characteristics and spectral properties of novel transparent lithium aluminosilicate glass-ceramics containing (Er,Yb)NbO4 nanocrystals

“…Among other Er-doped crystals [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15], erbium orthoniobates are promising luminescent materials [16,17]. Until now, several routes for their preparation were employed.…”

Comparison of the bond strength of composite resin to Er:YAG laser irradiated human enamel pre‐treated with various methods In Vitro

“…The Er:YAG laser was developed by Zharikov et al [1] in 1974 and was first applied to dentistry by Hibst et al in 1988 [2]. This laser can be used for effective removal of dentin and enamel [3].…”

WGM microresonators: sensing, lasing and fundamental optics with microspheres

“…Rare-earth ions such as ytterbium, erbium, samarium, neodymium and thulium are now popular optical gain dopants in modern solid-state lasers [76][77][78][79][80][81]. The first demonstration of a spherically symmetric, rare-earth doped, solid, whispering-gallery resonator undergoing lasing action was presented over forty years ago [82].…”
