Lasing behavior of sol-gel silica doped with UV laser dyes

Correlation between photophysical properties and lasing performances of Rhodamine-19 in three types of sol–gel glass hosts

“…The excellent properties of sol-gel glasses [2][3][4][5] have made these materials a good choice for host matrix to be used in the field of solid-state dye lasers. However, fluorescent dyes within the pores of silica gels usually show deviations from the characteristic fluorescent performance observed in the solution phase, which is typically considered as optimum [6][7][8][9][10][11][12][13][14].…”

Stable doped hybrid sol-gel materials for solid-state dye laser

“…Much research has already been devoted to solidstate dye lasers, because of their high laser efficiency and their technical and economical advantages. [1][2][3][4][5][6][7][8] Many different materials have been used as a solid host for organic dyes, such as methylmethacrylate based polymers, 2,9 -14 sol-gel glasses, 3,15 polycom glasses, 16,17 hybrid materials, 5,18 -24 and epoxy resins. 22 The key parameters concerning these materials are laser efficiency and photodegradation rate or lifetime.…”

Effect of higher protonation on lasing performance of Rhodamine-B in sol–gel glasses

“…The low temperature synthesized sol-gel glasses, amorphous and highly porous in nature, have attracted researchers for their use as host media because of excellent optical and mechanical properties [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. As far as laser damage threshold is concerned which should be high for a good host; sol-gel material is considered to have the highest value among polymer, polycomposite glass and ormosil (organically modified silicate) [20].…”
