Journal ArticleDOI
Laser Scanning Holographic Lithography for Flexible 3D Fabrication of Multi-Scale Integrated Nano-structures and Optical Biosensors
Liang Leon Yuan,Peter R. Herman +1 more
TL;DR: A laser scanning holographic method for 3D exposure in thick photoresist that combines the unique advantages of large area 3D holographic interference lithography (HIL) with the flexible patterning of laser direct writing to form both micro- and nano-structures in a single exposure step is introduced.
Journal ArticleDOI
Low-loss waveguides fabricated in BK7 glass by high repetition rate femtosecond fiber laser
Shane M. Eaton,Mi Li Ng,Jörn Bonse,Alexandre Mermillod-Blondin,Haibin Zhang,Arkadi Rosenfeld,Peter R. Herman +6 more
TL;DR: For the first time femtosecond-laser writing has inscribed low-loss optical waveguides in Schott BK7 glass, a commercially important type of borosilicate widely used in optical applications.
Journal ArticleDOI
Confocal Raman imaging of optical waveguides in LiNbO3 fabricated by ultrafast high-repetition rate laser-writing
TL;DR: The confocal Raman characterization of the micro-structural lattice changes induced during the high-repetition rate ultrafast laser writing of buried optical waveguides in lithium niobate (LiNbO(3)) crystals finds that the adjacent waveguide zone is largely free of defects.
Journal ArticleDOI
Raman gain from waveguides inscribed in KGd(WO4)2 by high repetition rate femtosecond laser
Shane M. Eaton,Clark A. Merchant,Rajiv Iyer,A.J. Zilkie,Amr S. Helmy,J.S. Aitchison,Peter R. Herman,D. Kraemer,R. J. D. Miller,Cyril Hnatovsky,Roderick S. Taylor +10 more
TL;DR: In this article, the formation of waveguides in Raman-active KGd(WO4)2 with a focused, high repetition rate femtosecond laser was reported.
Journal ArticleDOI
Vacuum ultraviolet laser spectroscopy III: laboratory sources of coherent radiation tunable from 105 to 175 nm using Mg, Zn, and Hg vapors
TL;DR: In this paper, nonlinear frequency mixing of laser radiation in Mg, Zn, and Hg vapors has produced coherent radiation, tunable over the range 175-104.5nm in the vacuum ultraviolet.
