We have developed a novel multiline infrared laser for dual-mode coherent/direct-detection Doppler/DIAL measurements of wind velocity and 3-D aerosol and chemical concentration. 2.02 μm and 3.4-3.6 μm tunable output are generated by a highly efficient Tm:LuAG-pumped PPLN OPO despite high idler absorption.
