Free stream jet for high power dye lasers

Tunable dye lasers with powers on the order of many tens of watts to several kW with emission linewidth stability on the order of 1/2 GHz will be required for commercial scale separation processes. To achieve these goals, several dye laser systems, both cw and pulsed, are presently under investigation at Livermore and other laboratories. Results of efforts to develop a free stream dye jet for incorporation into an incoherently pumped pulsed dye laser are presented. (U.S.)
