Abstract
We report on the application of a novel laser wavemeter1 to the measurement of both the mean wavelength and the spectral profile of a line-narrowed Alexandrite laser operating at PRF's in excess of 10 Hz. Wavemeters must be used as laser monitors in differential absorption lidar (DIAL) measurements of atmospheric pressure2, temperature3, and constituents4,5 where there is a strict requirement for good spectral registry between absorption lines (e.g., H2O, O2, and SO2) and the output of a pulsed laser.
