Originally published in Frontiers in Optics 2009/Laser Science XXV/Fall 2009 OSA Optics & Photonics Technical Digest, this article describes the creation mechanism of femtosecond laser produced silver microstructures in silver containing zinc phosphate glass.
A femtosecond is the SI unit of time equal to 10−15 of a second. That is one quadrillionth, or one millionth of one billionth, of a second.
It was shown that laser-induced depletion in a microstructure enables second harmonic generation exhibiting 2.44 times increased second-order susceptibility than quartz.
