Recently, the synthesis of infrared dyes of high photochemical stability became possible /1/. One of these dyes was used to operate a synchronously pumped cw dye laser system tunable around 1.3 μm /2/. Here we demonstrate a new method for effective pumping of dyes with small fluorescence quantum yield (10−4). Laser emission up to 1.8 μm is now accessible by a traveling wave pumping system.
