Concentration quenching anomalies of activated Y2SiO5:Pr3+ nanocrystal luminescence

303.5 nm cw Pr:BYF–BBO laser emission under 447 nm all-solid-state Nd:GdVO4–BiBO blue laser pumping

“…The laser crystal is one of the most important components of a solid-state UV laser. It is known that, thanks to more efficient radiative transitions, Pr 3+ doped crystals and glasses, including Pr 3+ doped fluorides [30], can be used to produce multicolor laser emissions for RGB (red, green, blue) applications [31][32][33][34][35][36][37][38][39][40]. The laser performance of Pr 3+ -ions has been reported [33,[41][42][43][44][45][46][47][48][49].…”

An efficient all-solid-state doubly resonant continuous-wave ultraviolet laser at 284 nm

“…The laser crystal is one of the most important components of a solid-state ultraviolet laser. It has been known for a long time that Pr 3+ -doped crystals and glasses and, among them, Pr 3+ -doped fluorides [13], thanks to more efficient radiative transitions, can be used to produce multicolor laser emissions for RGB (red, green, blue) applications. The laser performance of Pr 3+ -ions has been reported [14][15][16][17][18][19][20].…”

All-solid-state blue laser pumped Pr:KY3F10-BBO ultraviolet laser at 305 nm

“…It has been known since a long time that Pr 3+ doped crystals and glasses and, among them, Pr 3+ doped fluorides [32], thanks to more efficient radiative transitions, can be used to produce multicolor laser emissions for RGB (red, green, blue) applications. The laser performance of Pr 3+ -ions has been reported [33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52] [53]. To the best of our knowledge, the corresponding frequency doubled ultraviolet lasers have not been reported.…”
