Soliton Kerr Frequency Combs Generated in Integrated Photonic Chips

In 2007 a new method to generate optical frequency combs was discovered. In contrast to conventional frequency combs which are generated from pulsed laser sources, these Kerr frequency combs (also known as microresonator frequency combs) are generated enti ...

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 ...

Femtosecond laser direct-write waveplates based on stress-induced birefringence

Yves Bellouard, Christos Edouardos Athanasiou

The use of femtosecond lasers to introduce controlled stress states has recently been demonstrated in silica glass. We use this technique, in combination with chemical etching, to generate and control stress-induced birefringence over a well-defined region ...

750 nm 1.5 W frequency-doubled semiconductor disk laser with a 44 nm tuning range

Elyahou Kapon, Vladimir Iakovlev, Alexei Sirbu

We demonstrate 1.5 W of output power at the wavelength of 750 nm by intracavity frequency doubling a wafer-fused semiconductor disk laser diode-pumped at 980 nm. An optical-to-optical efficiency of 8.3% was achieved using a bismuth borate crystal. The wave ...

Laser-assisted morphing of complex three dimensional objects

Yves Bellouard, Jakub Drs

Morphing refers to the smooth transition from a specific shape into another one, in which the initial and final shapes can be significantly different. A typical illustration is to turn a cube into a sphere by continuous change of shape curvatures. Here, we ...

High-fidelity visualization of formation of volume nanogratings in porous glass by femtosecond laser irradiation

Yves Bellouard, Min Huang, Ya Cheng

Formation of self-organized nanogratings in bulk glasses with femtosecond laser pulses is one of the most intriguing phenomena in the interactions of light with transparent materials. With the feature sizes far beyond the optical diffraction limit, these n ...

Formation of nanogratings in a porous glass immersed in water by femtosecond laser irradiation

Yves Bellouard, Min Huang, Ya Cheng

Irradiation of intense ultrafast laser pulses in glasses can lead to formation of nanogratings whose periods are significantly smaller than the incident irradiation wavelength. The mechanism of the exotic phenomenon is still under hot debate. Here, we acce ...

Femtosecond resolution timing jitter correction on a TW scale Ti:sapphire laser system for FEL pump-probe experiments

Christoph Peter Hauri

Intense ultrashort pulse lasers are used for fs resolution pumpprobe experiments more and more at large scale facilities, such as free electron lasers (FEL). Measurement of the arrival time of the laser pulses and stabilization to the machine or other sub- ...
