Abstract

Textron Defense Systems (Formerly Avco Research Laboratory) has developed a kilowatt class dye laser. The device is a transverse flow, flashlamp pumped laser that operates at greater than 100 Joules per pulse, and at a repetition rate up to 10 Hz. Operating at 10 Hz, an average power of 1.04 kW was obtained at 585 nm using rhodamine 590 in a methanol/water solvent mixture. The output power was increased to 1.4 kW by adding the triplet quencher cyclooctatetraene to the solution. Under these conditions, the measured efficiency (average laser pulse energy/energy stored in flashlamp capacitors) was 1.8%. A limited series of experiments using alternative dyes was also carried out. Comparable energies and average powers were obtained at 610 nm using rhodamine 610, and 660 nm using sulforhodamine 640.
