Abstract
The tail of a carbon-dioxide (CO.sub.2) transverse electrode discharge at mospheric pressure (TEA) laser pulse optical signal is pulse code modulated by a Pockels Cell. A modulation depth of 100% is obtained to prevent high false alarm rates under dynamic transmission conditions. The device external to the laser cavity will extend the capabilities of the CO.sub.2 TEA laser by using a tail for information transfer while preserving the gain switch spike for rangefinding. A high repetition rate is achieved using a power supply that electrically charges and discharges the Pockels Cell which, in turn, activates the polarization switch.
