Effect of Excitation Wavelengths in Pulsed Dye Lasers.

New Dermatological Indications for Pulsed Dye Lasers

Laser therapy has been classically focussed on three different chromophores: haemoglobin, melanin, and water, based on selective photothermolysis theory. Despite the fact that therapy is evolving with the introduction of multiple new wavelengths and the description of more therapeutic targets, some laser devices, such as the pulsed dye laser (PDL), are still relevant in our clinical practice. B...

Laser-assisted hair removal: comparison of long-pulsed alexandrite and long-pulsed Nd:YAG lasers, individually and in combination

Background and aim: Laser is one of the most recent techniques which has widespread use in the treatment of many skin diseases. This technique has been successfully used to remove unwanted hairs in hirsutism. The aim of this study was to evaluate and compare the efficacy and safety of long-pulsed 755 nm alexandrite and long-pulsed 1064 nm Nd: YAG lasers individually and in combination for perma...

Fluidic fibre dye lasers.

We report the demonstration of compact fluidic fibre lasers based on capillary tubes and photonic crystal fibres, featuring single channel and multiple laterally integrated fluidic lasers respectively. Their preparation was based on capillary action and lasing occurred without the need for external mirrors or lithographically defined microstructures. The fibre lasers were found to be tunable by...

Optofluidic Dye Lasers

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...
