An efficient solid-state laser based on a nanoporous glass — polymer composite doped with phenalemine dyes emitting in the 600 — 660-nm region

Dye Doped Polymer-Filled Nanoporous Glass - a New Class of Materials for Laser Optics

“…As is seen in Fig.9 the FOC is distributed in the sample rather homogeneously. Location of the FOC in the PFNPG was found to be strongly dependent of its chemical nature: experimental studies of the FOC impregnation process showed that Rodamine 11B strongly adsorbed on pore surface, whereas the FOC of Pyrromethene series do not show the adsorption effect [15]. The efficiency of FOC impregnation to the composite may be characterized by the saturation coefficient of NPG in the monomer composition.…”

“…The Q-switchers [1,[8][9][10], lasing elements [11,[13][14][15][16][17][18][19][20][21], and laser radiation power limiters [22][23][24][25] have been made and successfully demonstrated to date. Other elements, such as the mode-lockers, can be also made by choosing a proper FOC.…”

“…Some results of the studies of this problem are presented below. These studies have been carried out with FOC of Pyromethene (PM 567, PM 580, PM 597, PM 650), Phenolemine (Ph 510, Ph 512, Ph 640), and some other series [9,10,13,15,16]. To investigate the homogeneity of FOC distribution in the PFNPG volume, transmittance of He-Ne laser radiation at 633 nm has been studied [12].…”

Lasing efficiency of dyes incorporated into a nanoporous glass-polymer composite

“…A disadvantage of these elements is their very low radiation resistance. Progress in this area began to be made in the 1980s after creation of solid-state matrices with high radiation resistance [2][3][4], and to date significant advances have been made in the field of solid-state dye lasers [5][6][7][8][9][10][11][12][13][14][15]. This is connected first of all with synthesis of new dyes and secondly with improvement of methods for introducing the dye into solid-state matrices [6].…”

“…In [10][11][12], the spectral luminescence and lasing characteristics were studied for solid-state active media based on laser dyes of different classes (coumarins, rhodamines, paraterphenyl) emitting in the visible and UV regions and incorporated into silicate bulk matrices, gel matrices, and thin films. It was concluded that use of such elements was promising in fast conducting devices and in design of microlasers.In [13][14][15][16], new active elements are proposed that are based on a dye-activated nanoporous glass-polymer composite (NPG-P). In [13,14], it is shown that NPG-P is a promising material for designing solid-state laser elements activated by organic dyes.…”
