Physical Review Letters, 2007 We investigate the effects of two dimensional confinement on the lasing properties of a classical random laser system operating in the incoherent feedback (diffusive) regime. A suspension of 250nm rutile (TiO2) particles in a Rhodamine 6G solution was inserted into the hollow core of a photonic crystal fiber (PCF) generating the first random fiber ...

Laser Technik Journal, 2014 AbstractFiber lasers have already firmly established themselves within the industrial production sector and are synonymous with efficiency, precision and cost‐effectiveness in a large number of laser material processing applications. They offer excellent single‐mode or multi‐mode beam qualities, which can be precisely adapted to the processing task and
