Four-wave-mixing-based optical parametric oscillator delivering energetic, tunable, chirped femtosecond pulses for non-linear biomedical applications.
TL;DR: A novel concept for an optical parametric oscillator based on four-wave mixing (FOPO) in an optical fiber that constitutes a stable, simple and in many ways superior alternative to bulk state-of-the-art OPO light converters for demanding biomedical applications and non-linear microspectroscopy.
Journal ArticleDOI
Fiber-based light sources for biomedical applications of coherent anti-Stokes Raman scattering microscopy
Thomas Gottschall,Tobias Meyer,Martin Baumgartl,Cesar Jauregui,Michael Schmitt,Jürgen Popp,Jürgen Popp,Jens Limpert,Andreas Tünnermann,Andreas Tünnermann +9 more
TL;DR: In this article, the authors summarize different fiber-based approaches for laser sources dedicated to coherent anti-Stokes Raman scattering (CARS) imaging, in particular active fiber technology and passive fiber based frequency conversion processes, such as supercontinuum generation, soliton self-frequency shift and four-wave mixing.
Journal ArticleDOI
62-W cw TEM00 Nd:YAG laser side-pumped by fiber-coupled diode lasers
TL;DR: The laser performance and thermal properties of side-pumped Nd:YAG rod lasers that use ibercoupled diode lasers as pump sources are described and optical slope efficiencies of more than 46% are observed.
Journal ArticleDOI
High power narrow-band fiber-based ASE source
O. Schmidt,Miroslaw Rekas,C. Wirth,Jan Rothhardt,S. Rhein,A. Kliner,Maximilian Strecker,Thomas Schreiber,Jens Limpert,Ramona Eberhardt,Andreas Tünnermann +10 more
TL;DR: A high power narrow-band amplified spontaneous emission (ASE) light source at 1030 nm center wavelength generated in an Yb-doped fiber-based experimental setup is described and a stimulated Brillouin scattering (SBS) suppression of at least 17 dB is demonstrated.
Journal ArticleDOI
57 W, 27 fs pulses from a fiber laser system using nonlinear compression
TL;DR: In this paper, a high average power fiber chirped pulse amplification (FCPA) system with a microstructured large-mode-area fiber for nonlinear compression is presented.
