Abstract
Diamond samples are irradiated with 140 fs pulses of 800 nm wavelength. The pulse repetition rate is 1 kHz. In the focal region of the irradiated pulses the diamond is transformed to graphite. The writing of graphitic wires along the incident beam is studied experimentally. A technique to produce buried graphitic wires with constant diameter is described. Diameters can be selected between 1.5 μm and 10 μm. The wire length is up to 680 μm. The writing speed is typically between 1 μm s−1 and 30 μm s−1.
