Although many people might imagine that the power density of a laser beam is the same at any point across the width of the beam, often that is not the case, with most single-mode lasers having a ...

A platform for inexpensive automatic laser beam profiling for finding the focal position and beam width of a laser beam, using a commercial translation stage, stepper motor, raspberry pi computer and ...

Fast photodetector and oscilloscope is used to measure laser pulse width. Traditional method uses beam splitting and calibrating to finish test. New test method can finish test detectly with precise ...

Previously, consequences on the radiobiological response by laser driven particle beams characterised by an ultra high peak dose rate have to be investigated. Therefore, tumour and non-malignant cells ...
