摘要

A new diode-laser-based UV-absorption sensor for high-speed detection of the hydroxyl radical (OH) is described. The sensor is based on sum-frequency generation of UV radiation at 313.5 nm by mixing the output of a 763-nm distributed-feedback diode laser with that of a 532-nm high-power, diode-pumped, frequencydoubled Nd: YVO_4 laser in a beta-barium borate crystal. Approximately 25 muW of UV radiation is generated and used to probe rotational transitions in the A~2SIGMA~+-X~2ll (v' = 0, v"= 0) electronic transition of OH. Singlesweep, single-pass measurements of temperature and OH concentration in a stoichiometric C_2H_4-air flame are demonstrated at rates up to 20 kHz.
