Laser Light-Induced Physical Processes In Optical Materials: Persistent Spectral Hole-Burning
Abstract
The paper reports the demonstration of FM spectroscopy with a multimode CW laser that in most cases preserves the high sensitivity of FM spectroscopy with a single-mode laser without the stringent alignment requirements. Sensitivity to absorptions as small as 0.0001 can be inferred from the measurements, and the restrictions on modulation frequencies for small sample times are explored.
