The design of a pulsed single-mode dye laser pumped by a copper vapour laser 13 presented. The experimental results using Rh6G, BhB and Kiten Bed S are given. The dye laser produces up to 200mW single-mode average power at an efficiency of over 4.5%. The linewidth. of the single-mode laser is 100MHz and its wavelength range is 563-642 nm.
