“…Organic gain media that have been successfully used for development of solid-state lasers and amplifiers fall under four broad categories: dye-doped polymers [4], organic semiconductors [3,[5][6][7][8], rare-earth ion doped polymers [9,10] and liquid crystals [11]. The first reports to date on such sources were of dye-doped polymers, in particular of Rhodamine G6 doped PMMA [12,13]. Laser operation in organic semiconductors was first reported for a fluorene single-crystal doped with anthracene, with the latter providing the stimulated emission [14].…”

Solid-state organic amplifiers and lasers are attractive for hybrid integration due to their compatibility with different material platforms, straightforward processing, and possibility to optimize easily their optical and electronic properties by molecular engineering. Advances in the gain medium design and synthesis in combination with new resonator architectures led to tremendous improvements in temporal and spectral properties, lifetime stability, gains produced and operating threshold powers, which triggered interest in their use for a broad range of integrated photonic applications. In this contribution, the current state-of-the-art in the field of organic solid-state amplifiers and lasers is reviewed from the aspects of fabrication technology, gain materials, and device performance. Furthermore, examples of the progress of this technology from a laboratory curiosity to one that demonstrates practical integrated photonic applications are highlighted. An outlook is also provided on research areas and applications that are likely to shape further developments of this technology. (Figure reprinted from [296],

We have used microsecond coherent pumping to study the lasing efficiency of active elements based on a nanoporous glass-polymer composite activated by organic dyes, as a function of the spectral composition of the pump within the main absorption band of the dye. We have shown that under the indicated excitation conditions, the lasing efficiency can exceed 40% and can be comparable with the lasing of liquid elements.Introduction. One disadvantage of lasers based on dye solutions is some inconvenience in operation associated with the fact that the active medium for this type of laser is a liquid. At the end of the 1960s, it was attempted to overcome this disadvantage using solid-state elements based on poly(methyl methacrylate) [1]. 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]. Many authors use various approaches to composite solid-state systems. In [7], the lasing efficiency was determined as a function of the intensity of excitation and the laser photostability of gel systems with dyes. It was shown that the efficiency of conversion of the pump radiation and laser photostability of the dyes in composite gel systems is higher than in simple gel matrices. In [8], the lasing properties of rhodamine 6G (the chloride and the perchlorate) were studied in synthesized hybrid polymers based on an organic polymer (methyl methacrylate with hydroxyethyl methacrylate) and an inorganic precursor (tetraethoxysilane). It was shown that active media based on hybrid polymers have significantly higher operating life compared with active media based on organic polymers, which is associated with formation of an inorganic nanostructural network in them and consequently with an improvement in the thermooptical properties of the material and weakening of the thermally initiated process of decomposition of the active molecules. In [9], a technology was developed for obtaining active polymeric optical fibers doped with organic dyes. It was shown that the lasing efficiency of rhodamine 11B in a polymeric optical fiber with cw pumping may be as high as 36%. 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 [13,1...

We present a compact solid-state laser based on leaky mode propagation from a dye-doped polymer free-standing film waveguide. The edge emitted spectrum clearly indicated the existence of periodic resonant modes. The reflections from the lateral faces of the free-standing film provided the optical feedback thus giving rise to a Fabry-Perot like optical cavity. This together with the guidance through the gain medium gave rise to intense narrow emission lines. For a pump energy of 1.82 mJ/pulse, an intense line with FWHM ∼0.4 nm was observed at 576.5 nm.

Stimulated Emission From Flashlamp-Excited Organic Dyes in Polymethyl Methacrylate

Abstract: Laser emission is reported from flashlamp-excited polymethyl methacrylate rods containing rhodamine dyes. Quenching of stimulated emission by the molecular triplet state is apparently reduced in the solid with respect to that observed for the same dyes in liquid solution.
