Semiconductor laser chip stabilization by Si3N4 microresonator and Kerr comb generation

Tobias Kippenberg, Andrey Voloshin, Mirjam Pfeiffer

The experimental study of the InPlaser diode stabilization by high-Q Si3N4 microresonator is presented. We demonstrate how this stabilized laser diode considered as a pump laser may be used for optical frequency comb generation in the same microresonator. ...

Octave-spanning dissipative Kerr soliton frequency combs in Si3N4 microresonators

Tobias Kippenberg, Michail Zervas, Junqiu Liu, Maxim Karpov, Hairun Guo, Martin Hubert Peter Pfeiffer, Erwan Guillaume Albert Lucas, Clemens Herkommer

Octave-spanning, self-referenced frequency combs are applied in diverse fields ranging from precision metrology to astrophysical spectrometer calibration. The octave-spanning optical bandwidth is typically generated through non-linear spectral broadening o ...

The formation of temporal dissipative Kerr solitons in microresonators driven by a continuous-wave laser enables the generation of coherent, broadband, and spectrally smooth optical frequency combs as well as femtosecond pulse sources with compact form fac ...

Dissipative Kerr solitons have recently been generated in optical microresonators, enabling ultrashort optical pulses at microwave repetition rates, that constitute coherent and numerically predictable Kerr frequency combs. However, the seeding and excitat ...

Dissipative Kerr solitons have paved the way to broadband and fully coherent optical frequency combs in microresonators. Here, we demonstrate numerically that slow frequency tuning of the pump laser in conjunction with phase or amplitude modulation corresp ...

Having accurate and comprehensive photon diagnostics for the X-ray pulses delivered by free-electron laser (FEL) facilities is of utmost importance. Along with various parameters of the photon beam (such as photon energy, beam intensity, etc.), the pulse l ...

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 ...
