Ultrafast lasers increase functionality of semiconductor chips

The method could exploit the sub-wafer surface space of chips to achieve higher integration densities and deliver extra functionality

Researchers achieve 'breakthrough' in the realisation of ultrafast quantum computers

An exceptionally fast qubit gate has been developed, representing completely new quantum computer hardware that breaks through the limitations of previous formats

Researchers 'write' in mid-air using ultrashort pulse lasers

Lasers have previously been able to produce optical illusions, however have required a dust/cloud medium in order to do so

Ultrafast gets ultra-small

Katrina Wesencraft outlines engineering and optical challenges involved in shrinking ultrafast lasers, all the way down to tiny devices for sending into space

Chromacity partners with Tematys

The new partnership will see Tematys align the technological sourcing requirements of French organisations with the capabilities of Chromacity’s ultrafast lasers
