Abstract

A review of current state of the art high energy and high average power flashlamp excited dye lasers is presented. Coaxial flashlamp dye laser designs have not changed significantly since they were first developed in 1968. However, there is now a better understanding on how to optimize operating parameters. New high brightness coaxial flashlamp excited dye laser systems can produce tunable ultraviolet radiation by means of second harmonic generation with high efficiency and output. Energy conversion efficiency over 16 percent has been measured at one joule input levels, and over one joule of ultraviolet light has been produced at a conversion efficiency exceeding ten percent. For high average power outputs greater than a 100 watts, the linear flashlamp excited dye laser is the preferred approach. Linear lamp dye lasers are intrinsically more efficient than coaxial lamp lasers,and pulsed electrical to laser output efficiency over 1.6 percent has been observed without the use of high dye concentrations. Except in a true waveguide dye laser, high concentration of the dye solution increases efficiency at the expense of beam quality. Design and performance parameters of a high brightness capillary cell, dye laser in terms of a beam quality figure of merit number R is described.
