Abstract
An experimental optimization of the efficiency of a gain switched tunable laser at is described. The thermal lensing during pulsed operation was measured. Optimal performance occurred at a crystal temperature of and resulted in an output energy of and a pulse duration of . Tunability in the range of , spectral linewidth of , and are demonstrated. The main laser material parameters are estimated. Such a laser could be employed in a laboratory-based nonscanning lidar system if a narrowband birefringent filter is installed. The tunability will permit the improvement of the transmitter for water-vapor differential absorption lidar if injection seeding is applied.
