We have investigated the intensity and phase noise of single-mode laser diodes, either free-running or using different types of line narrowing techniques at room temperature, namely feedback from an external grating and injection locking. We have mea

We have developed an atomic monitoring system for physical vapor deposition process control based on a frequency‐modulation (FM) spectroscopy scheme using a 670 nm external cavity diode laser. FM detection made it possible to measure absorption as

The process of making a measurement on a quantum-mechanical system introduces quantum noise to that system. A quantum nondemolition measurement scheme seeks to make a measurement of an observable to better than this quantum limit, by feeding all the

It is common practice to report measurements of weak optical signals in terms of the relative-intensity noise, which is essentially the ratio of the fluctuations to the average power. Typical experiments in which weak optical signals are measured inc

The free-induction decay (FID) technique combined with broadly tunable lasers offers a convenient way to survey molecular dephasing times. We measured FID's in molecular iodine by frequency switching an extended-cavity diode laser with a small curren

The intensity and polarization dependence of the ion production due to three quantum ionization was investigated in potassium. The energy of two of the photons was tuned into resonance with n2D levels for 4 < n < 22. The ratio of the ion signals prod

The diamagnetic Zeeman shifts of 2 S and 2 D Rydberg states of potassium were measured by Doppler-free two-photon absorption with fluorescence detection. Experimental results are found to agree excellently with theoretical values calculated using qua

The $3S\ensuremath{-}5S$ transition of Na atoms is induced by absorption of two photons, one each from two circularly polarized beams traveling in opposite directions through the vapor. The beams are derived from a tunable, narrow-band pulsed dye las
