Abstract


Along with the rapid development of electronic technology and laser technology in the field of defense and military the laser confrontation has become one of the competing countries in the development of key technologies . A battlefield laser threat represented by a laser rangefinder and laser target designator , is receiving increasing attention , in order to compete with them , and vigorously expand the laser warning investigative techniques . The analysis of these laser threat source , can be summed up to Nd : YAG laser as the core equipment plays an important role . Therefore, the study the repetition frequency encoding lasers suitable for simulation of these laser threats against technology experiments and test the performance of the laser warning machine is important for the conduct of the laser . The repetition frequency coding laser , a laser , electronic technology the military the photoelectric confrontation instrument outfield test experimental apparatus . Coded laser repetition frequency Nd: YAG lasers and optical Q- module as the core device clearance time of the laser output pulse code modulation , pulse encoder . To meet the main battlefield laser threat simulation requirements , so as to effectively detect the effectiveness of laser warning machine . Used of Ce: Nd : YAG crystal as the working substance of KDP crystal Q- device concave cavity laser pulse code laser head developed Ce3 ion Nd3 ion sensitized mechanism theory ; through the analysis the MPPM encoding draw this encoding initial information code is a one-to-one mapping relationship . Based on the the MPPM encoding , and use the CPLD implementation coding procedures designed ; Finally, the main index of the laser test and verify the design to meet the design requirements .
