Journal ArticleDOI
Femtosecond optical transfection of cells:viability and efficiency
D. J. Stevenson,B. Agate,X. Tsampoula,Patrick Tobias Fischer,Christian T. A. Brown,W. Sibbett,Andrew Riches,Frank J. Gunn-Moore,Kishan Dholakia +8 more
TL;DR: Contrary to recent literature, in which 100% efficiency is claimed, this measure of efficiency accounts for all irradiated cells, including those lost as a result of laser treatment, thereby providing a true biological measure of the technique.
Journal ArticleDOI
High-power picosecond and femtosecond pulse generation from a two-section mode-locked quantum-dot laser
Edik U. Rafailov,Maria Ana Cataluna,W. Sibbett,N. D. Il’inskaya,Yu. M. Zadiranov,A. E. Zhukov,Victor M. Ustinov,D.A. Livshits,A. R. Kovsh,Nikolai N. Ledentsov +9 more
TL;DR: In this paper, a two-section quantum-dot laser that produces output powers up to 45 mW at 1260 nm was demonstrated. The pulse duration could be varied from 2 ps to as short as 400 fs at the 21 GHz pulse repetition rate.
Journal ArticleDOI
Ultrafast electroabsorption dynamics in an InAs quantum dot saturable absorber at 1.3μm
TL;DR: In this article, a direct measurement of the absorption dynamics in an InAs p-i-n ridge waveguide quantum dot modulator was performed under reverse bias conditions, showing a decrease of nearly two orders of magnitude.
Journal ArticleDOI
Ultrashort-pulse lasers passively mode locked by quantum-dot-based saturable absorbers
Alexander A. Lagatsky,Christopher G. Leburn,Christian T. A. Brown,W. Sibbett,Svetlana Zolotovskaya,Edik U. Rafailov +5 more
TL;DR: In this article, some key recent achievements in the development of novel saturable absorbers that are based on semiconductor quantum-dot (QD) structures for the passive mode locking of near-infrared lasers are outlined.
Proceedings Article
Quantum-dot based saturable absorber with p-n junction for mode locking of solid-state lasers
Alexander A. Lagatsky,Edik U. Rafailov,W. Sibbett,D. A. Livshits,Alexey E. Zhukov,V.M. Ustinov +5 more
TL;DR: In this paper, stable mode locking in a Yb:KYW laser was demonstrated using a quantum-dot saturable absorber structure with p-n-junction, where a reduction in the output pulse duration was measured when a reverse bias was applied to SESAM.
