1200 lines/mm Gold-Coated pulse compression grating for 850–970 nm

The structural parameters and spectral performance of the pulse compression gratings are directly related to the design and output quality of high-power laser systems. In this paper, for the gold-coated gratings applicable to the 850–970 nm wavelength range, the effects of variat...

Modification Lemaitre Damage Accumulation Model with Metastable Austenitic Steels under Fatigue

Abstract A modification of the Lemaitre damage accumulation model that takes into account strain–induced martensitic transformation is proposed for metastable austenitic steels. The influence of the strain–induced martensite, accumulated microdamage and internal stresses on the d...
