A femtosecond laser that produces extremely short (280 femtoseconds \u2013 or 280 quadrillionths of a second) and intense pulses of light encrypts data file into layers of nanostructured dots inside a quartz glass. The layers are placed very close, with mere five micrometers (one millionth of a meter) between them.\u00a0\u00a0<\/p>\n<p style=\"margin:0 0 15px;padding:0;vertical-align:baseline;font-size:1.5em;line-height:1.4em;color:#000000;font-family:'Segoe UI', 'Gill Sans Light', Helvetica;font-style:normal;\">These light impulses modify polarization and refraction of self-assembled dots as the light travels through the glass, somehow similar to the principle used in polarized sunglasses.
