Abstract :
Summary form only given. Coherent all-solid-state light sources emitting broadly tunable UV radiation with high peak and average power are of fundamental importance for the remote sensing of various atmospheric constituents using the differential absorption lidar (DIAL) technique. It is advantageous to use tunable sources in order to adopt the on-line and off-line wavelengths to the specific absorption bands of the trace gas of interest. Tunable optical parametric oscillators (OPOs) pumped by the harmonics of Q-switched Nd:YAG lasers are therefore appropriate candidates potentially leading to reliable and compact systems.
