A rapid and reproducible procedure suitable for the analysis of polycyclic aromatic compounds (PACs) in sludges and soil samples has been developed. The PACs are isolated by ultrasonic extraction with methyl chloride, redissolution of the crude extract in isooctane and clean-up of the PAC-containing
output power is lower, as predicted by both approaches. When the reflectivity is small, the oscillation energy is small. Thus, the lasing wavelength has a lower number of photons available for feedback and energy accumulation. At higher reflectivities, although the energy within the cavity is large,
