suppressIon of fluorescence interference via wavelength shift keyed raman spectroscopy using an Argon Ion Laser and acousto optic tunable filter
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 1998Co-Authors: C M Stellman, F BucholtzAbstract:Abstract A wavelength shift-keyed (WSK) Raman spectrometer with Argon Ion Laser excitatIon, acousto-optic tunable filter (AOTF) wavelength modulatIon, and synchronous photon counting detectIon has been developed. It has been demonstrated that this novel approach to wavelength modulatIon spectroscopy results in suppressIon of unwanted fluorescence background while giving a substantial increase in signal-to-background over non modulatIon techniques. The relatively low cost, lack of complexity, and durability of the described system increases the utility of shift-keyed Raman spectroscopy to a broader base of users and ‘real world’ applicatIons.

transient heating and melting transformatIons in Argon Ion Laser irradiatIon of polysilicon films
Journal of Applied Physics, 1993Co-Authors: Xianfan Xu, Scott L Taylor, Hee K Park, Costas P GrigoropoulosAbstract:Undoped, thin silicon films have been deposited at different temperatures on fused quartz substrates by low‐pressure chemical vapor depositIon. The heating of these films by continuous wave, Argon‐Ion Laser beam irradiatIon has been studied. In situ, normal incidence reflectivity measurements have been obtained at specified locatIons in the semiconductor films. Melting and recrystallizatIon phenomena have been probed by transient measurements. The static film reflectivity at elevated temperatures, up to about 1400 K, has also been measured. The temperature field has been analyzed numerically, using a modified enthalpy model. Thin‐film optics were used to calculate the Argon‐Ion Laser light absorptIon in the polysilicon layer and the transient reflectivity response to the probing Laser light. The predicted and experimentally measured reflectivity histories have been compared. The initial stages of the phase change process have been captured by high‐speed photography.

fluorescence of na2 excited by the 4545 a line of the Argon Ion Laser
Journal of Quantitative Spectroscopy & Radiative Transfer, 1996Co-Authors: J J Camacho, J M L Poyato, A M Polo, A PardoAbstract:Abstract The fluorescence spectrum of Na 2 induced by the blue 4545.05 A line of an Argon Ion Laser has been observed and analysed for the first time. Four fluorescence series excited through the transitIons: v ′ = 20, J ′ = 51 ← v ″ = 2, J ″ = 50; v ′ = 27, J ′ = 71 ← v ″ = 4, J ″ = 71; v ′= 18, J ′ = 48 ← v ″ = 1, J ″ = 47 and v ′ = 17, J ′ = 58 ← v ″ = 0, J ″ = 57 were assigned in the B 1 II u → X 1 ∑ g + band system. The calculated radiative transitIon probabilities for the observed fluorescence series are in good agreement with measured relative intensities reported herein.
