Abstract

Our goal is to develop and characterize optical measurement technology to enable accurate quantification of greenhouse-gas emissions to meet the needs of industry and regulators. A 1064 nm pumped high energy optical parametric oscillator (OPO) operating from 1585 nm to 1646 nm was constructed for performing differential absorption LIDAR measurements of carbon dioxide, methane, and potentially nitrous oxide. The OPO uses a Rotated Image Singly-Resonant Twisted RectAngle (RISTRA) design. The commercially available RISTRA cavity is machined from a solid block of aluminum. The compact single piece cavity design requires no mirror adjustments and image rotation provides efficient conversion and excellent beam quality. The injection seeded OPO has demonstrated output energy of 45 mJ/pulse when pumped with 220 mJ/pulse of 1064 nm radiation. The pump laser has a repetition rate variable from 1 Hz to 100 Hz and a temporal pulse width of 4.2 ns. In the current configuration the seed laser is locked to a mode of the RISTRA cavity. The construction and performance of the OPO is discussed.
