Comparison of nanotip growth under different polarizations of laser pulses. SEM images of the glass target irradiated with circularly polarized pulses (a, b, c) and linearly (p-) polarized laser pulses (d, e, f); (a, d) 4 MHz, 0.25 ms; (b, e) 4 MHz, 0.5 ms; (c, f) 8 MHz, 0.25 ms; the pulse width used for all experiments was 214 fs.
