Singly-Resonant OPO for CO2/CH4 DIAL Transmitter for Use in Atmospheric Studies

Main Article Content

Chat Chantjaroen


We report on a singly-resonant optical parametric oscillator (OPO) based on periodically poled MgO-doped LiNbO3. The OPO was pumped by a Q-switch pulsed 1064-nm Nd:YAG laser and was seeded by an amplified 1571-nm DFB CW laser. The OPO is designed particularly for use as a laser source for a Differential Absorption Lidar (DIAL) for CO2/CH4 atmospheric concentration mapping. Maximum average output pulse energy of ~2 mJ and optical-to-optical conversion efficiency of up to ~20% have been achieved. Given the performance results of our frequency-agile OPO, we demonstrated a potential use of OPO in DIAL instruments for measurements of CO2 (1571 nm) and CH4 (1645 nm).
