Amplified spontaneous emission and optical gain measurements from pyrromethene 567--doped polymer waveguides and quasi-waveguides.
Amplified spontaneous emission from planar waveguides and quasi-waveguides based on Pyrromethene 567-doped poly(methyl methacrylate) thin films deposited onto quartz and glass substrates is investigated. Films with different thickness were prepared and pumped optically at 532 nm with pulses of up to 8 MW/cm(2). Pump thresholds for the onset of ASE emission, optical gains and losses were assesse...
متن کاملPerylene- and pyrromethene-doped xerogel for a pulsed laser.
Hydrophobic photostable dye molecules such as perylenes or pyrromethenes were trapped in xerogel matrices. Using these new materials as solid-state dye lasers, we have demonstrated efficient laser operation. Slope efficiencies of up to 30% were obtained in the millijoule output-energy range. Tunabilities of up to 60 nm were observed, and more than 150,000 pulses were emitted by the same spot of...
متن کاملLifetime, Efficiency and Photostability Enhancement of Pyrromethene Laser Dyes by Metallic Ag Nanoparticles
Complexation of metallic silver nano particles (NPs) with Pyrromethene laser dyes (PM567, PM597) has significant effect on lifetime, photostability and the fluorescence efficiency. These enhancement of optical properties of the complex in solution due to surface Plasmon resonance (SPR) have been promised higher efficiencies in case of [40% Ag NPs: PM dye] complexes for dye laser systems. The fl...
متن کامل8-PropargylaminoBODIPY: unprecedented blue-emitting pyrromethene dye. Synthesis, photophysics and laser properties.
Highly emitting 8-propargylaminoBODIPY (8-PAB) 2 was prepared in 94% yield. Unlike any other BODIPY structure hitherto described in the literature, 2 displays efficient emission in the blue region of the visible spectrum with a fluorescence quantum yield up to 0.94 and high laser efficiency (35%) at 483 nm.
متن کاملCharacteristics of a broadband dye laser using Pyrromethene and Rhodamine dyes.
A broadband dye laser pumped by a frequency-doubled Nd:YAG laser with a full width at half-maximum from 592 to 610 nm was created for the use in a dual-pump broadband coherent anti-Stokes Raman spectroscopy (CARS) system called width increased dual-pump enhanced CARS (WIDECARS). The desired broadband dye laser was generated with a mixture of Pyrromethene dyes as an oscillator gain medium and a ...
