Currently, continuous-wave powers as high as 20–25 watts can be reached with conventional single laser diodes, but the beam quality is extremely poor. PCSELs, however, can reach powers in the ...

The Epilog Laser Cutters use a high power CO2 laser for accurately engraving and cutting various materials. In the Maker Lab we have an Epilog Zing24 60 Watt laser cutter and an Epilog Zing24 40 Watt ...

The theory is deceptively simple The Heriot-Watt team also use high temperatures, but in a space measured in millionths of a metre. Their technique uses an ultrafast laser to deliver million watt ...
