Glycidyl methacrylate as a new host material for laser dyes

Abstract

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.

Experimental and theoretical study of optical properties of pyrromethene (PM‐597) laser dye in binary eco‐friendly solvent

“…Organic laser dyes dissolved in an appropriate organic solvent are considered the most habitually utilized laser media, because the active medium (liquid laser dyes) can be obtained in high optical quality and can be cooled by using a simple flow system. Furthermore, unlike a solid-state active medium, where damage is permanent, a liquid dye laser is selfrepairing., [3][4][5] but the conventional organic solvents have the shortcomings of volatility and flammability, which makes the dye laser risk to public health and the environment. Tackling this issue, ionic liquids have recently been proposed as a potential contender for eco-friendly solvents to replace volatile organic solvents.…”

“…[10] Ionic liquids (ILs) have a few favorable advantages over conventional organic solvents, such as negligible volatile, non-flammable, low vapor pressure, excellent thermal stability, and their high compatibility with various organic compounds and other materials, which make them environmentally compatible. [5,6,[11][12][13] Another important characteristic of the ionic liquids ILs is the ability of their molecular structure to be framed according to application requirements. [14] An almost infinite number of ionic liquids with specialized properties result from various combinations of cations and anions.…”

Photo-physical properties and amplified spontaneous emission of a new derivative of fluorescein

“…In recent years, the synthesis of new high-performance dyes and the implementation of new ways of incorporating the organic molecules into the solid matrix have resulted in significant advances towards the development of practical tunable solid-state dye lasers [7][8][9][10][11][12][13][14][15][16][17][18][19]. Most of the recent work in solid-state dye lasers has been done using either polymers, silica gels and glass-polymer composites [17] as host materials for lasing dyes.…”
