Regenerative similariton laser

Camille Sophie Brès, Thibault Emmanuel North

Self-pulsating lasers based on cascaded reshaping and reamplification (2R) are capable of initiating ultrashort pulses despite the accumulation of large amounts of nonlinearities in all-fiber resonators. The spectral properties of pulses in self-similar pr ...

Multi-mJ infrared femtosecond hydrogen Raman laser

Christoph Peter Hauri, Mostafa Shalaby

High-energy pulses at 1.28 mu m are demonstrated by stimulated Raman scattering in hydrogen using two chirped pulses of a Ti: Sapphire laser. The Stokes pulse carrying record-high energy of 4.4 mJ is recompressed to 80 fs. ...

Intense THz source based on BNA organic crystal pumped at Ti:sapphire wavelength

Christoph Peter Hauri, Mostafa Shalaby

We report on high-energy terahertz pulses by optical rectification (OR) in the organic crystal N-benzyl-2-methyl-4-nitroaniline (BNA) directly pumped by a conventional Ti:sapphire amplifier. The simple scheme provides an optical-to-terahertz conversion eff ...

85 W VECSEL output at 1270 nm with conversion efficiency of 59 %

Elyahou Kapon, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman

We report on 1270 nm vertical-external-cavity surface-emitting lasers (VECSELs) with up to 59% conversion efficiency and maximum output power of 8.5 W (pump limited), at 5 degrees C heat sink temperature. These VECSELs comprised wafer-fused gain mirrors in ...

TiO2 membrane high-contrast grating reflectors for vertical-cavity light-emitters in the visible wavelength regime

Georg Rossbach, Ehsan Hashemi

In this work, the authors describe a novel route to achieve a high reflectivity, wide bandwidth feedback mirror for GaN-based vertical-cavity light emitters; using air-suspended high contrast gratings in TiO2, with SiO2 as a sacrificial layer. The TiO2 fil ...

Intrinsic emittance reduction of copper cathodes by laser wavelength tuning in an rf photoinjector

Christoph Peter Hauri, Thomas Schietinger

With the improvement of acceleration techniques, the intrinsic emittance of the cathode has a strong impact on the final brightness of a free electron laser. The systematic studies presented in this paper demonstrate for the first time in a radiofrequency ...

Terahertz emission in organic crystals pumped by conventional laser wavelength

Christoph Peter Hauri

Intense Terahertz radiation in organic crystals is typically generated by optical rectification of short wavelength infrared femtosecond lasers between 1.3 and 1.5 μm. In this wavelength range high energy ultrashort pump sources are hardly available. Here ...

1 W at 785 nm from a frequency-doubled wafer-fused semiconductor disk laser

Elyahou Kapon, Alexandru Mereuta, Alexei Sirbu

We demonstrate an optically pumped semiconductor disk laser operating at 1580 nm with 4.6 W of output power, which represents the highest output power reported from this type of laser. 1 W of output power at 785 nm with nearly diffraction-limited beam has ...
