Single longitudinal mode lasing of coumarin-doped sol-gel silica laser

Development of Nanocomposite Alpha-Detectors Based on Silica Matrices and Organic Scintillators

“…Density and porosity of the silica matrices determined by the method of hydrostatic weighing were 1.40 g/cm 3 and 54 vol.%, respectively. The average value of the microhardness was 170 kg/mm 2 , which is practically two times higher than the values reported by different authors [10,11].…”

Efficient lasing action from Rhodamine-110 (Rh-110) impregnated sol–gel silica samples prepared by dip method

“…Several types of materials have been used as host matrices for dye encapsulation [1][2][3][4][5][6][7][8]. Recently, researchers have shown intense interest in the use of low temperature sol-gel technique to prepare solid-state laser materials [4][5][6][7][8][9][10][11][12][13]. Also improved photostability of dye in solgel materials has been reported [4][5][6][7][8][9][10][11][12][13][14][15].…”

Also improved photostability of dye in solgel materials has been reported [4][5][6][7][8][9][10][11][12][13][14][15]. Various laser dyes, belonging to Xanthene and Coumarin classes, have been used as dopant in the past for the preparation of dye doped sol-gel solidstate active material [4][5][6][7][8][9][10][11][12][13].…”

“…In addition to commercial advantages, these lasers have technical advantages over liquid dye lasers. Several types of materials have been used as host matrices for dye encapsulation [1][2][3][4][5][6][7][8]. Recently, researchers have shown intense interest in the use of low temperature sol-gel technique to prepare solid-state laser materials [4][5][6][7][8][9][10][11][12][13].…”

Spectroscopic study of sulforhodamine 640-doped sol–gel silica

“…Organic dye molecules as laser gain media enjoy the advantage of broad tunability ranging from 300-900 nm with high efficiency, high photostability and superior thermal-optical properties. Reports on the spectroscopic behaviours [6,7], lasing properties [6,[8][9][10][11][12][13][14][15][16] and optical non-linearities [17] of a large number of dyes trapped in sol-gel-derived silica glasses have already appeared in the literature. The applications of tunable solid-state laser in visible are in remote sensing, isotope separation, high sensitivity analytical spectroscopy and underwater communications.…”
