Simulation Technology for Advanced Laser Processing Machines

Measurements of the energy spectrum of electrons emanating from solid materials irradiated by a picosecond laser

Heat accumulation during pulsed laser materials processing.

Laser materials processing with ultra-short pulses allows very precise and high quality results with a minimum extent of the thermally affected zone. However, with increasing average laser power and repetition rates the so-called heat accumulation effect becomes a considerable issue. The following discussion presents a comprehensive analytical treatment of multi-pulse processing and reveals the...

Recent Development in Laser Materials Processing

Recent research and development in laser machining and laser forming processes is reviewed. In the laser machining area, striation formation and prediction, and gas jet workpiece interactions are discussed. In the laser forming area, strain rate effects, and convex forming are presented.

Bayesian Spectrum Analysis for Laser Vibrometry Processing

Laser vibration sensing provides a sensitive non-contact means of measuring vibrations of objects. These measurements are used in industrial quality control and wear monitoring as well as the analysis of the vibrational characteristics of objects. In laser vibrometry, the surface motion is monitored by heterodyne laser Doppler velocimetry, and the received heterodyne signal is sampled to produc...
