Laser ablation via programmable image projection for submicron dimension machining in diamond
Laser ablation via programmable image projection for submicron dimension machining in diamond
A digital micromirror device is used as an intensity spatial light modulator, in conjunction with a femtosecond laser, for programmable image-projection-based laser ablation of polycrystalline diamond. Results show the machining of complex structures on the diamond surface, where individual structures have submicron features, covering a total area of 10×10µm and fabricated using ten laser pulses. This dynamic image-based machining technique may offer speed advantages over serial-writing procedures, whilst still producing wavelength-scale feature sizes.

Abstract
A digital micromirror device is used as an intensity spatial light modulator, in conjunction with a femtosecond laser, for programmable image-projection-based laser ablation of polycrystalline diamond. Results show the machining of complex structures on the diamond surface, where individual structures have submicron features, covering a total area of 10×10µm and fabricated using ten laser pulses. This dynamic image-based machining technique may offer speed advantages over serial-writing procedures, whilst still producing wavelength-scale feature sizes.
