摘要
We report the generation of femtosecond Bessel beams of conical half-angle 26 degrees using an axicon lens and a beam reduction imaging setup. The generated Bessel beams were applied to the micromachining of nanostructures in glass of length up to 100 μm. The effect of the incident pulse energy on the characteristics of the nano- structures was studied using optical microscopy.
