Journal ArticleDOI
Observation of optical coupling in microdisk resonators
Carsten Schmidt,Arkadi Chipouline,Thomas Käsebier,Ernst-Bernhard Kley,Andreas Tünnermann,Thomas Pertsch,Vladimir Shuvayev,Lev I. Deych +7 more
TL;DR: In this article, the spectral response and light intensity distribution along the coupled disks were measured and it was found that the distribution depends on the particular excited resonance, which can be attributed to the formation of normal modes of the coupled resonator system.
Journal ArticleDOI
2 MHz repetition rate, 200 ps pulse duration from a monolithic, passively Q-switched microchip laser
TL;DR: In this article, a monolithic passively Q-switched microchip laser with a repetition rate of up to 2 MHz was presented, which is the highest ever reported from such laser operating in the sub-ns regime.
Journal ArticleDOI
High-repetition-rate sub-5-fs pulses with 12 GW peak power from fiber-amplifier-pumped optical parametric chirped-pulse amplification
Steffen Hädrich,Stefan Demmler,Jan Rothhardt,Christoph Jocher,Jens Limpert,Andreas Tünnermann +5 more
TL;DR: A high-energy fiber chirped-pulse amplification system operating at 1 mJ pulse energy and nearly transform-limited pulses is used to achieve ultrabroadband amplification in two 2mm beta-barium borate crystals.
Book ChapterDOI
New Concepts for Diode-Pumped Solid-State Lasers
TL;DR: Two very promising examples of these new concepts of solid-state lasers, namely the fiber laser and the thin-disk laser, which have attracted much attention recently are focused on.
Journal ArticleDOI
Fiber-amplifier pumped high average power few-cycle pulse non-collinear OPCPA.
Franz Tavella,A. Willner,Jan Rothhardt,Steffen Hädrich,Enrico Seise,Stefan Düsterer,Th. Tschentscher,Holger Schlarb,Josef Feldhaus,Jens Limpert,Andreas Tünnermann,Joerg Rossbach +11 more
TL;DR: This work reports on the performance of a 60 kHz repetition rate sub-10 fs, optical parametric chirped pulse amplifier system with 2 W average power and 3 GW peak power, to their knowledge the highest average power sub- 10 fs kHz-amplifier system reported to date.
