Solid-state dye lasers based on copolymers of 2-hydroxyethyl methacrylate and methyl methacrylate doped with rhodamine 6G

Lasing characteristics of Rhodamine B and Rhodamine 6G as a sensitizer in sol–gel silica

“…The laser conversion efficiency of Rh. 6G-doped sol-gel silica laser is higher than that reported in other references [27,[35][36][37][38][39].…”

“…This high stability of Rh. B is greater than the stability of other laser dyes reported in [45][46][47][48][49], and comparable to that reported in [50,51]. The efficiency, defined as the ratio between energy of Rh.…”

High-repetition-rate polymeric solid-state dye lasers pumped by a copper-vapor laser

“…Further improvements would require fine tuning of the properties of the matrix. As our previous studies on polymeric solid-state dye lasers have demonstrated, 1,11,14 the composition and properties of the matrix are of uppermost importance to optimize the laser performance of a given dye. Work in progress seems to indicate that a copolymer formulation in which PETA is substituted by pentaerythritol tetraacrylate could result in laser emission from dye PM567 with improved photostability while maintaining efficiency.…”

“…Rh6G was dissolved in a copolymer of MMA and 2-hydroxyethyl methacrylate ͑HEMA͒ in vol/vol proportion 1:1, which was the material that in our previous work on solid solutions of Rh6G in methacrylate polymers we had found produced the best laser results. 14 The solid laser samples were disks 25 mm in diameter and 2 mm thick, with a 2-mm-diam hole in the center of the disk used to attach the sample to the shaft of a continuous motor rotating at about 20 Hz. The rotating disk was mounted on a horizontal translation stage which was driven by a second motor with a circular cam to produce 1 Hz sinusoidal lateral motion.…”

Amplified Spontaneous Emission of Side-pumped Step-index Rh640 perchlorate-dye-doped Polymer Optical Fiber

“…Organic dye-doped POFs have the advantages of non-volatile, non-flammable, nontoxic, compact, and mechanically stable. Because of these advantages, increasing number of studies on solid-state POF lasers and amplifiers [1][2][3][4][5][6][7][8][9][10][11][12][13] has been carried out for two decades.…”
