We simulate adaptive feedback control to coherently shape a femtosecond infrared laser pulse by means of a 4f-spatial light modulator in order to selectively excite the rovibrational modes of a polyatomic molecule. We preferentially populate an arbit

The acronym MLIS (molecular laser isotope separation) defines the laser process whereby the isotopes of uranium can be separated by mid-infrared laser/s when the molecule employed is UF6. The theoretical and spectroscopical data to configure and enab

The controlled radiation from a TEA CO 2 laser is important in many applications. One of the important parameters is its bandwidth and a simple technique for fast measuring and monitoring it is presented.

A numerical model of a three-mirror resonator for a TE CO(2) laser was developed. This model was used to determine if a three-mirror resonator with an etalon could be used to ensure tunable single-mode action on the lower gain lines of CO(2). Single-

SUMMARY A detailed description is given of an annealing system in which transmission electron microscope specimens can be heat-treated for known effective annealing times at accurately known constant temperatures. The apparatus includes facilities fo

Multiple-faulted dislocation loops formed in pure aluminium and aluminium alloys during quenching have in the past been considered as having a layered structure. Very recently an alternative coplanar structure was supported by Westmacott. Theoretical

It is demonstrated how a quantitative study of some anomalous thin‐foil annealing phenomena, if interpreted correctly, leads to the determination of important physical constants. The necessary theory is developed and applied to measure the activati

SUMMARY The general principles laid down by Swart & Kritzinger (1974a) in a paper dealing with the unfaulting of Frank dislocation loops by the simultaneous action of two shearing Shockley dislocations are applied to explain the structure and electro
