Acousto-optic pulse picking scheme with carrier-frequency-to-pulse-repetition-rate synchronization.

Optics express

de Vries O, Saule T, Plötner M, Lücking F, Eidam T, Hoffmann A, Klenke A, Hädrich S, Limpert J, Holzberger S, Schreiber T, Eberhardt R, Pupeza I, Tünnermann A.
PMID: 26367616
Opt Express. 2015 Jul 27;23(15):19586-95. doi: 10.1364/OE.23.019586.

We introduce and experimentally validate a pulse picking technique based on a travelling-wave-type acousto-optic modulator (AOM) having the AOM carrier frequency synchronized to the repetition rate of the original pulse train. As a consequence, the phase noise characteristic of...

Femtosecond Enhancement Cavities in the Nonlinear Regime.

Physical review letters

Holzberger S, Lilienfein N, Carstens H, Saule T, Högner M, Lücking F, Trubetskov M, Pervak V, Eidam T, Limpert J, Tünnermann A, Fill E, Krausz F, Pupeza I.
PMID: 26207470
Phys Rev Lett. 2015 Jul 10;115(2):023902. doi: 10.1103/PhysRevLett.115.023902. Epub 2015 Jul 08.

We combine high-finesse optical resonators and spatial-spectral interferometry to a highly phase-sensitive investigation technique for nonlinear light-matter interactions. We experimentally validate an ab initio model for the nonlinear response of a resonator housing a gas target, permitting the global...

Divided-pulse nonlinear compression.

Optics letters

Klenke A, Kienel M, Eidam T, Hädrich S, Limpert J, Tünnermann A.
PMID: 24322082
Opt Lett. 2013 Nov 15;38(22):4593-6. doi: 10.1364/OL.38.004593.

We report on the nonlinear pulse compression of temporally divided pulses, which is presented in a proof-of-principle experiment. A single 320 fs pulse is divided into four replicas, spectrally broadened in a solid-core fiber, and subsequently recombined. This approach...

Temporal contrast enhancement of energetic laser pulses by filtered self-phase-modulation-broadened spectra.

Optics letters

Buldt J, Müller M, Klas R, Eidam T, Limpert J, Tünnermann A.
PMID: 28957121
Opt Lett. 2017 Oct 01;42(19):3761-3764. doi: 10.1364/OL.42.003761.

We present a novel approach for temporal contrast enhancement of energetic laser pulses by filtered self-phase-modulation-broadened spectra. A measured temporal contrast enhancement by at least seven orders of magnitude in a simple setup has been achieved. This technique is...

Adaptive pre-amplification pulse shaping in a high-power, coherently combined fiber laser system.

Optics letters

Becker NC, Hädrich S, Eidam T, Just F, Osvay K, Várallyay Z, Limpert J, Tünnermann A, Pertsch T, Eilenberger F.
PMID: 28957160
Opt Lett. 2017 Oct 01;42(19):3916-3919. doi: 10.1364/OL.42.003916.

We report on the successful implementation of an adaptive pre-amplification pulse shaping technique in a high-power, coherently combined fiber laser system to achieve sub-300-fs pulse durations at 320 W average power and 3.2 mJ pulse energy. The pulse shaper...

The Sense of Agency Scale: A Measure of Consciously Perceived Control over One's Mind, Body, and the Immediate Environment.

Frontiers in psychology

Tapal A, Oren E, Dar R, Eitam B.
PMID: 28955273
Front Psychol. 2017 Sep 12;8:1552. doi: 10.3389/fpsyg.2017.01552. eCollection 2017.

The sense of agency (SoA) is defined as "the registration that I am the initiator of my actions." Both "direct" and "indirect" measurement of SoA has focused on specific contextualized perceptual events, however it has also been demonstrated that...

Prevalence and Incidence of Syphilis among Volunteer Blood Donors in Israel.

Journal of blood transfusion

Vera L, Milka D, Nurith SL, Eilat S.
PMID: 24860686
J Blood Transfus. 2014;2014:154048. doi: 10.1155/2014/154048. Epub 2014 Apr 22.

Data of 1,290,222 volunteer blood donors, in a 5-year period, was analyzed for prevalence and incidence of syphilis. Subsequent testing of donations positive in Treponema pallidum hemagglutination assay included Venereal Disease Research Laboratory and fluorescent Treponemal antibody absorption. Stepwise...

Power scaling of a high-repetition-rate enhancement cavity.

Optics letters

Pupeza I, Eidam T, Rauschenberger J, Bernhardt B, Ozawa A, Fill E, Apolonski A, Udem T, Limpert J, Alahmed ZA, Azzeer AM, Tünnermann A, Hänsch TW, Krausz F.
PMID: 20548383
Opt Lett. 2010 Jun 15;35(12):2052-4. doi: 10.1364/OL.35.002052.

A passive optical resonator is used to enhance the power of a pulsed 78 MHz repetition rate Yb laser providing 200 fs pulses. We find limitations relating to the achievable time-averaged and peak power, which we distinguish by varying...

High energy ultrashort pulses via hollow fiber compression of a fiber chirped pulse amplification system.

Optics express

Hädrich S, Rothhardt J, Eidam T, Limpert J, Tünnermann A.
PMID: 19259232
Opt Express. 2009 Mar 02;17(5):3913-22. doi: 10.1364/oe.17.003913.

A simple, robust and compact pulse compressor for a high-repetition rate high-peak power fiber chirped pulse amplification system is presented. We use noble-gas-filled hollow fibers for spectral broadening of the optical pulses via self-phase modulation. Subsequent compression with chirped...
