... (SPI) is also capable of ionizing aliphatic compounds if the VUV wavelength is short enough and, thus, has a somewhat complementary selectivity profile with respect to REMPI. SPI-TOFMS gives a survey over the (volatile) organic contents of the sample and exhibits a rather broad field of potential applications ...

... 100 series, for example, typically delivers 500 mJ of energy per pulse at 248 nm (Fig.4). Better beam characteristics A large, uniform beam profile with steep edges provides maximal use of the target, uniform ablation and smooth deposition. (If beam fluence falls off significantly near the edges, then ...

... as linear interpolations from those in Ref. 25, and a bowing factor of 2.05 eV is used for calculating the band-gap energy of InGaN. The band-edge profiles shown in Fig. 2 correspond to the boundary condition of a periodical field distribution (Fw) ( Pb Pw) ·Lb /(Lw Lb)26 with a flat surface, and b ...

... electrical-to-optical system efficiency since diode lasers emit optical energy over a narrow spectrum that closely matches solid-state absorption profiles. Additionally, reducing thermal gradients in the solid-state gain media improves beam quality and laser performance. The lifetime of high-power semiconductor ...

... the internal field (Fw) of sample b on the carrier injection density (Ninj). The underlying physics is that the originally saw-tooth-like band-edge profile can provide a nonvanishing, first-order correction in the interband transition energy when a perturbation, such as carrier injection, to the internal ...

... primary laser pulse intensity, I, as described by the equation, s In, where n is at least 2. Furthermore, other laser beam parameters, such as beam profile quality, divergence, or coherence, have a strong influence on the output signal. Therefore, careful control of the laser parameters is crucial for ...
