Abstract
NASA has been deeply involved in the development of new LIDAR instruments to be used as atmospheric probes. One important application is for DIAL measurements of water vapor and oxygen content at different altitudes. LaserGenics Corp. has been involved in the development of a tunable Ti:Al203 laser oscillator for NASA Langley Research Center. The primary goals of our program are an oscillator with a linewidth of less than one picometer at each of three wavelengths, 724 nm , 760 nm , and 940 nm , with greater than 25 mJ of output energy per pulse at a repetition rate of 10 Hz. We will describe our oscillator design and how such problem areas as wavelength tuning, optical damage, astigmatism and conversion efficiency were overcome. Finally we will report the results achieved with the laser.
