Phase-stable, multi-μJ femtosecond pulses from a repetition-rate tunable Ti:Sa-oscillator-seeded Yb-fiber amplifier
We present a high-power, MHz-repetitionrate, phase-stable femtosecond laser system based on a phase-stabilized Ti:Sa oscillator and a multi-stage Ybfiber chirped-pulse power amplifier. A 10-nm band around...
PublicationsUltrafast optomechanical pulse picking
State-of-the-art optical switches for coupling pulses into and/or out of resonators are based on either the electro-optic or the acousto-optic effect in transmissive elements. In high-power applications,...
PublicationsExtraction of enhanced, ultrashort laser pulses from a passive 10-MHz stack-and-dump cavity
Periodic dumping of ultrashort laser pulses from a passive multi-MHz repetition-rate enhancement cavity is a promising route towards multi-kHz repetition-rate pulses with Joule-level energies at an unparalleled...
PublicationsEnhancement cavities for few-cycle pulses
We address the challenge of increasing the bandwidth of high-finesse femtosecond enhancement cavities and demonstrate a broad spectrum spanning 1800 cm−1 (195 nm) at −10 dB around a central wavelength...
PublicationsTailoring the transverse mode of a highfinesse optical resonator with stepped mirrors
Enhancement cavities (ECs) seeded with femtosecond pulses have developed into the most powerful technique for high-order harmonic generation (HHG) at repetition rates in the tens of MHz. Here, we demonstrate...
PublicationsActive intensity noise suppression for a broadband mid-infrared laser source
Excess relative intensity noise (RIN) constitutes one of the major limitations of most spectroscopic methods involving lasers. Here, we present an active RIN suppression scheme for a coherent mid-infrared...
PublicationsGeneration of isolated attosecond pulses with enhancement cavities — a theoretical study
The generation of extreme-ultraviolet (XUV) isolated attosecond pulses (IAPs) has enabled experimental access to the fastest phenomena in nature observed so far, namely the dynamics of electrons in atoms,...
PublicationsThree-octave terahertz pulses from optical rectification of 20fs, 1μm, 78MHz pulses in GaP
We demonstrate optical rectification of 1 ìm pulses with a duration of 20 fs, a repetition-rate of 78 MHz and an average power of 5.5 W, in a 2 mm thick GaP crystal. The spectrum of the resulting far-infrared...
PublicationsVelocity- and pointing-error measurements of a 300 000-r/min self-bearing permanent-magnet motor for optical applications
Compact, ultra-high-speed self-bearing permanent-magnet motors enable a wide scope of applications including an increasing number of optical ones. For implementation in an optical setup, the rotors have...
PublicationsHigh-power frequency comb at 2 μm wavelength emitted by a Tm-doped fiber laser system
We report on the generation of a high-power frequency comb in the 2 ìm wavelength regime featuring high amplitude and phase stability with unprecedented laser parameters, combining 60 W of average power...
