Optical tagging methods have the advantage that they cannot be detected by a suspicious criminal or terrorist using a radio frequency (RF) sensitive device to scan his vehicle for the presence of an RF emitting tag. We will describe two optical taggi

An analysis methodology and corresponding analytical tools for rapid top-down design of multi-spectral imaging systems is presented. Beginning with top- level customer-dictated system performance requirements and constraints, the critical system and

A novel glass rhomb has been demonstrated for separating the residual fundamental beam from the harmonic beam in a frequency-doubled or frequency-tripled laser. This device features simple fabrication, damage resistance of uncoated glass, essentially

The new method of atomic fluorescence detection, called saturated optical nonresonant emission spectroscopy (SONRES), has been modeled for a three-level atom, and experiments on sodium have been conducted that support the model. A rate equation analy

The atomic vapor quantum counter (AVQC) offers the potential for efficient upconversion of narrow-band IR radiation. This paper explores wavelength tuning of the AVQC by the application of an electric field (Stark effect). Model calculations indicate

We have demonstrated the extremely small detection limits that can be achieved in a high‐pressure environment by the combination of saturated absorption and nonresonance emission spectroscopy. The method of SONRES exploits efficient energy transfer

An efficient technique for the detection of nartowband infrared radiation by up-conversion in an optically saturated atomic vapor is described. The strong transition cross sections provided by the resonance interactions combined with the narrow Doppl

The stimulated emission cross section of the 1.061‐μm transition (R1—Y1) in Nd: YAG has been measured and is (5.1 ± 0.5) × 10−19 cm2 on the same scale that assigns the value 8.8 × 10−19 cm2 to the 1.064‐μm line. The thresholds of the 1

Saturated Optical Nonresonance Emission Spectroscopy (SONRES) has been applied to metallic vapor detection. Using one-photon cw excitation less than 0. 2 atoms of sodium have been detected in the laser interaction volume with an ambient pressure envi
A new method of detection has been developed for analysis of metallic atoms in the gas phase. The method relies on Saturated Optical NonResonance Emission Spectroscopy (SONRES) to provide efficient fluorescence analysis in an ambient pressure environ
