Tobias Meyer,Mario Chemnitz,Martin Baumgartl,Thomas Gottschall,Torbjörn Pascher,Christian Matthäus,Bernd F. M. Romeike,Bernhard R. Brehm,Jens Limpert,Andreas Tünnermann,Andreas Tünnermann,Michael Schmitt,Benjamin Dietzek,Jürgen Popp +13 more
TL;DR: A novel near-infrared (NIR) fiber laser of 1 MHz repetition rate, 65 ps pulse duration, and 1 cm(-1) spectral resolution is reported to realize an efficient but experimentally simple SGH/TPEF/multiplex CARS multimodal imaging approach for a label-free characterization of composition of complex tissue samples.
Journal ArticleDOI
Toward laser welding of glasses without optical contacting
Sören Richter,Felix Zimmermann,Ramona Eberhardt,Andreas Tünnermann,Andreas Tünnermann,Stefan Nolte,Stefan Nolte +6 more
TL;DR: In this paper, the authors used bursts of ultrashort laser pulses with an individual pulse energy of up to 10 MPa to fill the gap between the two samples and determined the breaking strength of laser-welded fused silica samples without an intermediate layer or an optical contact.
Journal ArticleDOI
5D hyperspectral imaging: fast and accurate measurement of surface shape and spectral characteristics using structured light
TL;DR: The design and implementation of a 5D sensor operating in the visible to near-infrared spectral range is described, which provides excellent spatial and spectral resolution, great depth accuracy, and high frame rates.
Journal ArticleDOI
Thermal properties of borate crystals for high power optical parametric chirped-pulse amplification.
R. Riedel,Jan Rothhardt,Kolja Beil,B Gronloh,Arno Klenke,Hauke Höppner,Michael Schulz,Ulrich Teubner,Christian Kränkel,Jens Limpert,Andreas Tünnermann,Mark J. Prandolini,Franz Tavella +12 more
TL;DR: The potential of borate crystals, BBO, LBO and BiBO, for high average power scaling of optical parametric chirped-pulse amplifiers is investigated and up-to-date measurements of the absorption coefficients at 515 nm and the thermal conductivities are presented.
Journal ArticleDOI
Klein tunneling of light in waveguide superlattices
TL;DR: In this paper, the authors present an experimental observation of Klein tunneling of light waves in lattices of evanescently coupled waveguides with a superimposed potential step, where the incident wave packet mass is generated by a minigap in the band structure of the lattice.
