New cascade laser transitions of (CH2F2)C-12 at 172.50-mu-m, 208.83-mu-m, 220.44-mu-m, 223.99-mu-m and 250.61-mu-m are reported. A waveguide FIR laser was pumped with a quasi cw (CO2)-C-12-O-16 laser operating on the 9R32 line. Together with the already kn ...
Laser-induced CVD has been used to produce Pt lines on pyrex glass substrates by means of platinum bis(hexafluoroacetylacetonate) as precursor. The effect that writing speed has on the line geometry and resistivity was studied, as well as the influence of ...
Laser generated defects in (Al,Ga) As have been investigated by photochemical wet etching and TEM measurements. Photoetching reveals a 500 nm wide zone in the center of the processed area where according to laser power either a luminescent or a nonradiativ ...

We report the first LIF spectrum of the SiC free radical. The SiC molecules are produced using pulsed-laser vaporization of silicon in combination with a supersonic expansion. The spectrum observed around 410 nm is assigned as C 3-PI(upsilon' = 3)-X 3-PI(u ...
The efficiency of classical gas-dynamic isotope sepn. can be strongly improved with the aid of a relatively weak IR laser. Irradn. in the collisional region of a free jet of SF6 dild. in Ar with a 20-W CO2 laser leads to an increase in the overall enrichme ...
Microscopic ohmic contacts are made by laser chem. vapor deposition of platinum on a Pyrex substrate. The elec. cond. of the deposited metal stripes is measured as a function of the laser power, the writing speed, and the organometallic vapor pressure. The ...
A laser-induced depostion technique is used to produce platinum interconnection lines for microelectronic applications. The influence of the laser power as well as the vapor pressure of the precursor upon the geometry, the morphol. and the line resistivity ...
SF6 in a free jet was vibrationally excited by a continuous-wave CO2 laser. The subsequent energy transfer processes, in which vibrational energy is degraded, lead to changes in the beam's spatial, velocity and cluster-size distributions. These changes wer ...
The feasibility of a new, 2-laser, isotope sepn. scheme was tested. The 1st laser induces isotopically selective condensation in the collisional region of a free jet of SF6 dild. in Ar. Thus, a mol. beam contg. non-clustered 32SF6 and clustered 34SF6{m}Ar{ ...
An argon laser is used to induce Laser Chem. Vapor Deposition (LCVD) of platinum using platinum bihexafluoroacetylacetonate as precursor. The process can be photolytic or pyrolytic depending on the laser power used. These processes are studied by recording ...
