“…In [115] it was shown that the introduction of even a small amount [(1-10)·10 -4 M] of Rhodamine 6G (R6G) slightly reduces the rate of copolymerization at the initial stage of the process. A similar effect is found in Rhodamine B, oxazines (1) and (17) [116] and copolymers of 2-hydroxyethyl methacrylate (HEMA) and MMA with laser dyes [117].…”

The main factors affecting the degradation of dyed polymeric matrices by the action of light (conversion of light energy into thermal energy, electron phototransfer, population of triplets, aggregation of dyes, oxidation-reduction processes, interaction with oxygen, including singlet) are analyzed and classified. Their dependence on the structure of the dyes, the nature of the polymer, and the method of dyeing of the latter is examined. Criteria for the creation of lightfast dyed matrices are formulated. Special attention is directed to contemporary light-sensitive materials in which the dye is covalently bonded to the polymer and to organic-inorganic compositions based on them.Dyed polymers are widely used in laser technology [1][2][3][4][5], media for writing and recording data [6-8], solar power [9][10][11][12], and optoelectronics [12][13][14][15]. Such polymeric materials have a series of operational advantages over dyed liquid materials on account of their more simple and more convenient construction, non-toxicity, and the possibility of working over a wide temperature range (from minus to plus temperatures) and under conditions of weightlessness. However, these advantages can only be realized to the full extent in the solution of various applied problems if dyed matrices with sufficient stability to the action of light are created. The aim of the present review was therefore to analyze, classify, and generalize methods of creating such matrices. FACTORS GIVING RISE TO THE DEGRADATION OF DYED POLYMERS DURING THE ACTION OF LIGHTThe presence of absorbing microimpurities that are heated by radiation are responsible for the radiation damage of optically transparent polymers. Purification from such inclusions at the monomer stage leads to a substantial increase in the threshold of radiation damage in the obtained polymer. For instance, the purification of methylmethacrylate (MMA) by repeated slow distillation raises this threshold of polymethylmethacrylate (PMMA) from several times [16] to two orders of magnitude [17]. 0040-5760/09/4503-0143

“…Rods 20 mm in length and 10 mm in diameter were ground and polished to the required optical quality. The bulk density of the rods was 1.86 g/cm 3 . We checked the internal optical quality of the undoped polymer rods by passing a He-Ne laser beam of 2 mW and 632.8 nm through the rods, where no dispersion or distortion of the laser beam was observed.…”

This article reports on the laser action of pyrromethene 597 and pyrromethene 567 doped in the novel solid polymeric matrix glycidyl methacrylate. Mirrorless lasing was observed when samples with diameters of 10 mm and lengths of 20 mm, with different dyes concentrations, were transversely pumped at 532 nm. The influence of the dye concentration on the laser measurements included the peak wavelengths, output energies, conversion efficiencies, and laser gains. Relatively high lasing efficiencies (up to $ 60%) were obtained from these new polymeric materials with very good photostability, where a decrease of only 65% in the initial laser output energy was observed after pumping by 60,000 shots of 15 mJ at 10 Hz.

“…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].…”
