“…For the latter transition, the 4 G 9=2 level was populated by a three-ion process originating in the excited 4 I 9=2 level. This is in contrast to the previously reported violet emission [9,10] that originated in the 2 P 3=2 level when different up-conversion pumping was employed.…”

“…The visible fluorescence in Er 3þ -doped ZBAN (ZrF 4 -BaF 2 -AlF 3 -NaF) and ZB(L)AN (ZBANLaF 3 ) glasses [3,4] has been studied in detail with the green and the red bands [5][6][7][8] attracting considerable attention. Various blue and violet lines, originating from the 2 P 3=2 , 2 H 9=2 and 4 F 7=2 levels, have also been reported in Er 3þ -doped fluoride fibers [9,10] and bulk glasses [6] under various excitation conditions.…”

“…When the ZBLAN fiber is pumped with red lasers, Er 3+ ions is excited to the 4 F 9/2 level and then relax to the 4 I 11/2 and 4 I 13/2 levels from which sequential ESA with pump photons results in populating on 2 P 3/2 and 4 S 3/2 levels. Green, blue, and violet emissions can be achieved through the radiative decays from the 4 S 3/2 and 2 P 3/2 levels [142]. Pope et al [143] observed an efficient violet upconversion signal from an Er 3+ -doped ZBLAN fiber pumped at 633.5 nm.…”

-NaF), considered as the most stable heavy metal fluoride glass and the excellent host for rare-earth ions, has been extensively used for efficient and compact ultraviolet, visible, and infrared fiber lasers due to its low intrinsic loss, wide transparency window, and small phonon energy. In this paper, the historical progress and the properties of fluoride glasses and the fabrication of ZBLAN fibers are briefly described. Advances of infrared, upconversion, and supercontinuum ZBLAN fiber lasers are addressed in detail. Finally, constraints on the power scaling of ZBLAN fiber lasers are analyzed and discussed. ZBLAN fiber lasers are showing promise of generating high-power emissions covering from ultraviolet to mid-infrared considering the recent advances in newly designed optical fibers, beam-shaped high-power pump diodes, beam combining techniques, and heatdissipating technology.

“…[42] Nonetheless, two-photon fluorescence resonance energy transfer is not the only process which can indirectly lead to blue-shifted fluorescence in rare earth materials at high levels of excitation. [43][44][45] There are other competing mechanisms for such observations, each involving energy transfer between three chromophore/fluorophore sites, with two acting as donors and one as acceptor. For an overview of three-body in the context of other photophysical processes involving lanthanides the reader is referred to a review by Auzel.…”

It is shown how key features of natural photosynthesis can be emulated in novel materials based on photoactive multichromophore arrays and crystals. A major consideration in the design of such systems is the means of channeling electronic excitation from sites of light absorption to centers where it is stored or released. Storage is often achieved by driving charge separation or, for the longer term, a more complex chemical reaction whilst rapid release is commonly associated with frequency up-converted emission. In each case channeling to the conversion site generally entails a multi-step energy transfer mechanism whose efficiency is determined by the arrangement and electronic properties of the array chromophores or ions, guided in the more complex systems by a spectroscopic gradient that promotes overall directionality. The functional cascade molecules known as photoactive dendrimers are exemplars of this approach. The latest developments involve new mechanisms for concerted excitation transfer in multichromophore systems, leading towards the tailoring and exploitation of optical nonlinearities for high intensity energy pooling applications.
