Abstract

The frequency tuning and stabilization of a novel long-pulse seeded Nd:YAG laser is described. The laser frequency was stabilized to ±8 MHz by locking it to an iodine absorption. A Doppler-free experiment shows the laser linewidth to be in good agreement with the Fourier transform limit of 10 MHz. Molecular hyperfine frequencies and parameters were determined for three I₂ absorption lines. The use of this laser as a pump and a cw probe amplifier for coherent anti-Stokes Raman spectroscopy is illustrated by a scan of the 2ν₂ Q-branch transition in CO₂, and the instrumental resolution is found to be 43 ± 15 MHz.
