Ultrafast laser processing uses laser bursts on the femtosecond scale to effect join together two objects with heat. The use of ultrashort laser burst prevents the heat from spreading to the surroundings, and interfering with the material's properties. This allows for extreme precision, and allows materials such as glass and metal to be welded together.
Dr. Richard Carter graduated from the University of Edinburgh in 2005 with an MPhys, from the University of St-Andrews and Heriot-Watt jointly with a MSc in photonics and optoelectronic devices in 2007 and from the University of Heriot-Watt in 2012 with a PhD. His PhD studies involved the development and investigation of long period fibre gratings as hydrogen sensors in close collaboration with AWE. In 2012 he joined the high power laser applications group at Heriot-Watt as a research associate.
Dr Carter has studied high-power laser manufacturing processes and fibre optics in Heriot-Watt, Edinburgh and St Andrews Universities. Recent research projects have included: high power beam delivery with novel hollow core fibres; fibre optic sensing; micro material processing including machining, drilling and welding; and most recently microwelding of highly dissimilar materials.
