Ultrafast laser direct writing (ULDW) is explored as a facile technique to induce
unprecedented physical phenomena and functional structures three dimensionally in glass …

Femtosecond laser micromachining can be used either to remove materials or to change a
material's properties, and can be applied to both absorptive and transparent substances …

High-repetition rate femtosecond lasers are shown to drive heat accumulation processes
that are attractive for rapid writing of low-loss optical waveguides in transparent glasses. A …

The extremely high peak intensity associated with ultrashort pulse width of femtosecond
laser allows us to induce nonlinear interaction such as multiphoton absorption and tunneling …

This paper provides an overview of the rather new field concerning the applications of
femtosecond laser microstructuring of glass to optofluidics. Femtosecond lasers have …

When a femtosecond laser pulse is focused inside a transparent material, the optical
intensity in the focal volume can become high enough to induce permanent structural …

The interaction of intense femtosecond laser pulses with transparent materials is a topic that
has caused great interest of scientists over the past two decades. It will continue to be a …

A variable (0.2 to 5 MHz) repetition rate femtosecond laser was applied to delineate the role
of thermal diffusion and heat accumulation effects in forming low-loss optical waveguides in …

Abstract 20 years ago, volume nanogratings in silica glass were discovered upon ultrafast
laser irradiation. Since then, these extraordinary self-organised and birefringent structures …

Although mainstream grating writing, more often than not using single photon excitation of
germanosilicate based defects with CW 244 nm light, remains the key technology for …
