| Research Abstract |
Two technical issues for the practical lidar to measure the vertical profile of the atmospheric carbon dioxide (CO_2) are remained. One is the receiving system with high sensitivity and the other is the stable laser with high power output. To solve these issues, two technical development were executed. For the receiving system, the receiver using the highly sensitive new solid state device, which is developed quite recently, are developed and the device are confirmed to be adopted into the lidar receiver. The optical parametric generator laser with out any resonator using the high gain device is newly developed for the transmitter. The experimental system has the very high power output with very high stability . The output power and the stability of the system are confirmed to be usable for the CO_2 lidar system.
