Abstract
Abstract The invention is a laser head for simultaneous pumping several dye lasers with a single flashlamp. The laser head includes primarily a multi-elliptical cylinder cavity with a single flashlamp placed along the common focal axis of the cavity and with capillary tube dye cells placed along each of the other focal axes of the cavity. The inside surface of the cavity is polished. Hence, the single flashlamp supplies the energy to the several dye cells.
