We report on the development of a custom optical parametric oscillator (OPO) pumped by a burst-mode laser to study flow and combustion parameters in high-speed flows. Current work focuses on an architecture that enables the excitation of carbon monoxide (CO) species via burst-mode two-photon laser induced fluorescence (TP-LIF). The OPO design enables narrowband (0.5 cm\textsuperscript{-1}) output without the use of an external seed laser, providing tunability to reach electronic transitions of CO. High conversion efficiency is critical for detecting CO near 230.1 nm for studies of boundary layer characteristics for a range of surface conditions. The OPO design is described, along with preliminary data confirming its operation and potential for species detection. Further data on the performance of the fluorescence imaging system will be acquired for a variety of pressures of interest in high-speed flows, followed by application to the Boeing/AFOSR Mach 6 Quiet Tunnel (BAM6QT) at the Aero Sciences Lab at Purdue University.
