Tunable polymer dye laser pumped by two 513 nm diodes

Abstract

We demonstrate a tunable solid-state polymer dye laser with quasi-longitudinal pumping by two green (λ = 513 nm) laser diodes. Tuning curves with a maximum efficiency of 13% were attained, using a plate of crystalline quartz (Lyot filter) for wavelength selection. In a threemirror cavity with partial compensation of astigmatism, the total tuning range was 62 nm (from 545 nm to 607 nm) for pyrromethene dyes: PM567, PM580 and PM597. The best results were achieved with active elements based on Pyrromethene 580 laser dye in a mixture of polyvinyl butyral or a copolymer of butylmethacrylate and methacrylic acid (ratio 9:1) with the addition of 30% dibutylsebacinate as a plasticizer.

Diode-pumped all-fiber-optic liquid dye laser

“…A LD pumping source has advantage in regard to the price, the size and the energy consumption compared to the frequency-doubled ones used in previous works [3][4][5][6][7][8][9]. We also have demonstrated a LD pumping through an optical fiber transversely in regard to the optical axis of the resonator, which is an alternative to the direct LD pumping demonstrated in previous works [10][11][12][13][14][15][16][17][18][19][20][21][22][23]. Thus we can take the advantages of the basic structure used, as we have demonstrated in [24], and with the help of fiber micro-optics could create a miniature fully integrated all-fiber-optic dye laser.…”

“…Dye lasers that are excited by LDs and that operate in the visible wavelength range have been demonstrated over the years. To provide feedback in these lasers, distributed Bragg reflectors [10][11][12][13][14][15][16][17][18], distributed feedback reflectors [19,20], dichroic mirrors and two-dimensional photonic crystal resonators [21][22][23] are used for example. Even the operation of the pumping LD using rechargeable nickel metal hydride batteries has been demonstrated [21].…”

“…The active medium in diode pumped dye lasers generally is excited directly by focusing the radiation from the LD [10][11][12][13][14][15][16][17][18][19][20][21][22][23]. The use of optical fibers in the pumping system would allow the creation of a compact all-fiber-optic dye laser source.…”

Tunable co-doped dye laser of coumarin 440 and coumarin 460

“…Tunable dye lasers in the spectral range from the visible to ultraviolet are of considerable interest for various applications, from laser physics to molecular spectroscopy [4,5]. In the visible region, particularly in the range of 500-700 nm, dye lasers are convenient [6]. While there are still some spectral regions which are not easily accessible.…”
