The article focuses on the usage of shorter laser pulses in micromachining. It mentions that wavelength dependence is more important at long pulse lengths and as the pulse lengths get shorter, the wavelength dependence is minimized. It notes that successful micromachining of a material requires a material that efficiently absorbs light at the laser output wavelength. Moreover, it determines that shorter pulses produce cleaner results.
