    Notes: Abstract We describe a new and highly effective optical frequency discriminator and laser stabilization system based on signals reflected from a stable Fabry-Perot reference interferometer. High sensitivity for detection of resonance information is achieved by optical heterodyne detection with sidebands produced by rf phase modulation. Physical, optical, and electronic aspects of this discriminator/laser frequency stabilization system are considered in detail. We show that a high-speed domain exists in which the system responds to the phase (rather than frequency) change of the laser; thus with suitable design the servo loop bandwidth is not limited by the cavity response time. We report diagnostic experiments in which a dye laser and gas laser were independently locked to one stable cavity. Because of the precautions employed, the observed sub-100 Hz beat line width shows that the lasers were this stable. Applications of this system of laser stabilization include precision laser spectroscopy and interferometric gravity-wave detectors.

    Dye-laser frequency stabilization using optical resonators (1984)

    Notes: Abstract We describe a study, performed using heterodyne techniques, of the frequency fluctuations of two completely independent ring dye lasers locked to independent reference cavities. Single laser linewidths of less than 750 Hz were achieved, the principal limitation being residual vibrations from the noisy laboratory environment. With future design and environmental improvements, ultranarrow linewidths are expected thus providing a useful tool for a great variety of high precision experiments.

    Notes: Abstract The fluorescence and lasing characteristics of 25 oxazole dyes have been investigated. Lasing was attempted using flashlamp pumping with and without the presence of oxygen. A few of the dyes showed the highest laser lifetimes covering the wavelength region of 495–523 nm that we have ever tested. Other dyes showed high laser outputs. Many of the dyes had useful flashlamp-pumped laser characteristics using water as the solvent. Although the best lasing conditions were observed in the absence of oxygen, good lifetimes could be obtained under air for solvents such as ethanol/water.
