Optofluidic dye lasers refer to a class of liquid dye lasers, usually on a microfabricated device, in which the adaptive nature of the liquid gain medium allows the dynamical control of the laser properties. Miniaturizing liquid dye lasers onto a microfluidic device not only results in compact, easy-to-maintain and safe dye laser systems, but also provides unprecedented optical performances suc...

We demonstrate a two-directional tuning method of distributed feedback (DFB) film dye laser devices to achieve high quality lasing and a large tuning range. In this work, we proposed a simple method to fabricate a continuous tunable solid-state dye laser on a flexible Polydimethylsiloxane (PDMS) film. In order to obtain stable and tunable output lasing, the stretching property of the gelatine h...

A rhodamine 6G dye laser, internally pumped within the extended cavity of an Ar(+)-ion laser, is mode locked when its cavity length is matched to half that of the pump laser: the 5145-A argon laser line is passively mode locked by the combination of the saturable absorption and the lasing action of the dye, which is in turn synchronously pumped and mode locked. Tunable (5650-5950-A) ~10 psec pu...

Cryotherapy has similar cure rates to topical salicylate (a pharmacologic therapy) for nongenital common warts (strength of recommendation [SOR]: B, based on systemic review of variable quality randomized trials). Duct tape may be equivalent to cryotherapy (SOR: B, based on a single randomized trial). CO2 laser, photodynamic therapy, pulsed dye laser (PDL), and Er:Yag laser therapies may also b...

The role of the saturable absorber dye DDI in the cw passively mode-locked Ti:sapphire/DDI laser both with and without compensation prisms is investigated. This laser self-starts when the concentration of the dye is greater than -2 x 10M for both picosecond and femtosecond pulses. With the prism pair, the laser generates Gaussian pulses 150 fs in duration. The corresponding spectrum is sech in ...

BACKGROUND Several studies have reported positive results of nonablative laser treatment of xanthelasma palpebrarum, but the published evidence is weak and inconclusive. OBJECTIVE To systematically evaluate the effect of pulsed dye laser (PDL) treatment of xanthelasmas. MATERIALS AND METHODS Twenty female Caucasian patients with 38 lesions (< or =1 mm above skin level) were enrolled. They r...

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 ...

The generation of broadly tunable, narrow linewidth. high power radiation in the near infrared is important for a number of scientific applications. The infrared radiation may be utilized as a spectroscopic source or in laser-matter interactions that require a high power. wavelength tunable light source. Frequency doubling of the near infrared radiation leads to a tunable source of high spectra...

We present a laterally emitting, coupled cavity micro fluidic dye ring laser, suitable for integration into lab-on-a-chip micro systems. The micro-fluidic laser has been successfully designed, fabricated, characterized and modelled. The resonator is formed by a micro-fluidic channel bounded by two isosceles triangle mirrors. The micro-fluidic laser structure is defined using photo lithography i...
