The Strategic Defense Initiative Organization has conducted a successful demonstration of a laser radar in a discrimination test against a dummy warhead launched by a sounding rocket. Called Firefly, the experiment was designed to determine the laser radar's ability to identify unarmed decoys that might be dispersed to defeat a strategic defense system. The tracking device, known as Firepond, is a high-power, wideband, isotopic carbon dioxide laser radar. Infrared wavelength signal is amplified by a narrowband pulsed carbon dioxide amplifier. The frequency is modulated with a SSB modulator and further amplified by a high-power electron beam sustained discharge, pulsed wideband laser amplifier. The use of carbon-13 isotope gives the laser better atmospheric performance with less distortion.
