Blue laser dye spectroscopic properties in solgel inorganic-organic hybrid films.
A blue solid-state laser material based on 4,4' dibenzyl carbamido stilbene-2,2' disulfonic acid incorporated into solgel zirconia and inorganic-organic hybrid matrices is presented. The absorption maxima of the dye in various matrices are around 339-361 nm, and the broad fluorescence peaks are at 411-413 nm. Optical gain measurements using the variable stripe method show amplified spontaneous emission peaking at 437 nm.
