Abstract

To assist in the design and development of high power Hydrogen Fluoride laser systems Aculight has developed a novel, compact, widely tunable spectroscopic source specifically for operation in the 2.4 to 2.8-micron wavelength region. This source is a continuous wave (CW), room temperature, single frequency, diode-pumped, doubly resonant optical parametric oscillator (DRO). The spectroscopic capabilities of the OPO have been demonstrated by scanning its frequency through absorption features of carbon dioxide at 2.7 microns. We have also characterized the effects of water vapor absorption in this wavelength region upon the performance of the source. In addition to measuring key HF laser parameters this widely tunable mid IR source has significant utility in a wide array of applications including sensing and combustion diagnostics.
