Femtosecond laser direct-write photoconductive patterns on tellurite glass
Gözden Torun, Anastasia Romashkina, Tetsuo Kishi +1
We report the formation of arbitrary photoconductive patterns made of tellurium (Te) nanocrystals by exposing a tellurite (TeO2-based) glass to femtosecond laser pulses. During thi…
Femtosecond laser-shockwave induced densification in fused silica
Arunkrishnan Radhakrishnan, Julien Gateau, Pieter Vlugter +1
Tightly focused femtosecond laser-beam in the non-ablative regime can induce a shock-wave enough to reach locally pressures in the giga-Pascal range or more. In a single beam confi…
Wavelength-multiplexed single-shot ptychography
Jonathan Barolak, David Goldberger, Jeff Squier +3
Diagnostics capable of interrogating dynamics in harsh environments such as plasma have remained essentially unchanged in recent decades. Developments in advanced microscopy techni…
Optomechanical suspended waveguide for broadband phase modulation with frequency memory effect
Enrico Casamenti, Tao Yang, Pieter Vlugter +1
Whether it is for transmitting information or for controlling intensity, light modulation is among the essential functions commonly used in complex optical systems. In integrated o…
Femtosecond laser direct-write waveplates based on stress-induced birefringence
Ben McMillen, Christos Athanasiou, Yves Bellouard
The use of femtosecond lasers to introduce controlled stress states has recently been demonstrated in silica glass. We use this technique, in combination with chemical etching, to…
Formation of in-volume nanogratings with sub-100 nm periods in glass by femtosecond laser irradiation
Yang Liao, Wangjun Pan, Yun Cui +4
We present direct experimental observation of the morphological evolution during the formation of nanogratings with sub-100-nm periods with the increasing number of pulses. Theoret…
Plasma waves excited at interface by femtosecond laser irradiation enabling formation of volume nanograting in glass
Yang Liao, Jielei Ni, Lingling Qiao +4
Irradiation of intense ultrafast laser pulses in glasses can lead to formation of nanogratings whose periods are significantly smaller than the incident irradiation wavelength. The…
On the anisotropy of stress-distribution induced in glasses and crystals by non-ablative femtosecond laser exposure
Ben McMillen, Yves Bellouard
Femtosecond laser exposure in the non-ablative regime induces a variety of bulk structural modifications, in which anisotropy may depend on the polarization of the writing beam. In…
