When lasers are used to heat most materials, the energy from the laser first heats up the electrons in the target. These in turn heat up the ions, making the process slower than targeting the ions directly. … This method puts energy straight into the ions,” said the paper’s lead author, Dr Arthur Turrell.

What is laser heating?

Laser heating and resistance heating are two heating methods that are commonly used in heat-assisted microforming processes. … The spot size of the laser can be controlled by the distance from the lens to specimen surface. The nature of laser heating is to change the internal microstructure of metal by energy absorption.
