“…In the last decades the technology of solid-state dye lasers has made some substantial technical advances, like expanded tunable ranges and higher output power together with better power stability [2,3]. Via an intra-cavity second harmonic generation process with liquid dye lasers the realization of a tunable continuous wave (CW) UV laser source have been reached in 1971 [4].…”

We describe a high power CW solid-state dye laser setup. With perylene orange in PMMA as gain medium an output power up to 800 mW at 576 nm and a tuning range between 565 and 595 nm is reached. The laser output shows good long time power stability. The durability can be adjusted by variation of the pump power. A feedback loop controls the laser output. At a setpoint of e.g. 100 mW, the laser output can be provided for more than eight hours with a low noise level (RMS < 10%). The spectral width of the laser emission is less than 3 GHz and can be tuned over more than 30 nm. A circular mode-profile is achieved with M2 < 1.4 [1].Via intra-cavity second harmonic generation more than 1 mW of 290 nm UV-radiation is achieved. As nonlinear element a 7 mm BBO (Beta-Barium Borate) crystal is used. The UV laser radiation can be tuned over 10 nm. The theoretical limit of UV output is estimated to 3.5 mW. To our knowledge we present the first tunable CW polymer UV laser.While the output stability at the fundamental wavelength is reasonably good, in the UV region a significant enhancement of the noise level is observed. In addition to this the long time stability is reduced to few minutes. The limitation is mainly given by the photo-decomposition of the organic dye molecules.

Electrically pumped organic lasers have been a challenge for years. The most crucial problem is that the density of charge carriers is much lower than the threshold required for lasing as compared with optical pumping. Apparently, increasing the density of charge carriers and reducing the threshold are two practical routes for solving the problem. Reducing the pump threshold depends strongly on the structural design and the operation‐mode control in the device. Here, a large‐area array of microcavities is employed to construct the light‐emitting diodes (LEDs) using distributed Bragg gratings (DBGs) as high‐efficiency reflectors and the homogeneous poly[(9,9‐dioctylfluorenyl‐2,7‐diyl)‐alt‐co‐(1,4‐benzo‐(2,1′,3)‐thiadiazole)] films in‐between as the active cavity body. Simultaneous lasing of multiple longitudinal modes at optical pumping verifies the optical feedback and oscillation mechanisms in such DBG‐based microcavities. Further successful construction of light‐emitting diodes using these microcavity arrays and the observation of narrowing of the electroluminescence spectrum due to the selectivity by the microcavities and the increase of the excitation electrical field suggest that the LED design here defines a promising step toward electrically pumped polymer lasers.

We report on results of design and fabrication of a microfluidic dye laser that consists of a ring resonator, a waveguide for laser emission output, and microfluidic elements for flow control, all integrated on a chip. The optical resonator and the waveguide were obtained by photolithography, whereas microfluidic elements such as channels, valves, and pumps were fabricated by multilayer soft lithography. As results, the prototype device worked with a few nanoliters of Rhodamine 6G dye molecules in ethanol solution and showed a laser threshold of ∼15μJ∕mm2 when optically pumped with a frequency doubled Nd:YAG laser at 532nm wavelength. The modification of the laser output intensity due to photobleaching effect was characterized by changing the dye flow velocity through the cavity. In addition, the emission wavelength of the laser could be easily tuned by changing the dye molecule concentration with the integrated microfluidic elements.
