Self-referencing turns pulsed laser systems into self-referenced frequency combs. Such frequency combs allow counting of optical frequencies and have a wide range of applications. The required optical bandwidth to implement self-referencing is typically ob ...

Erbium doped random fiber laser and fiber mixing effect

Luc Thévenaz, Camille Sophie Brès, Can Yao

We demonstrate an active random fiber laser by directly pumping a 100 m erbium-doped fiber at 980 nm wavelength, with a fiber loop mirror forming a half-open cavity. Random lasing with competing spectral modes in the range from 1535 nm to 1560 nm is achiev ...

Coexistence of Multiple Nonlinear States in a Tristable Passive Kerr Resonator

Miles Henry Anderson

Passive Kerr cavities driven by coherent laser fields display a rich landscape of nonlinear physics, including bistability, pattern formation, and localized dissipative structures (solitons). Their conceptual simplicity has for several decades offered an u ...

Raman Self-Frequency Shift of Dissipative Kerr Solitons in an Optical Microresonator

Tobias Kippenberg, Victor Brasch, Michail Zervas, Michael Wolfgang Geiselmann, Maxim Karpov, Hairun Guo, Martin Hubert Peter Pfeiffer, Arne Kordts

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 ...

Versatile High Repetition Rate 2-μm Pulsed Source Based on Wideband Parametric Conversion

Camille Sophie Brès, Adrien Billat, Steevy Joyce Cordette

We report an all-fiber pulsed source based on parametric conversion followed by thulium amplification able to deliver picosecond pulses at a repetition rate selectable between 2 and 5 GHz, of which central wavelength can be freely selected in the 2-μm regi ...

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 ef ...

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 ...

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 ...

Temporal solitons in optical microresonators

Tobias Kippenberg, Victor Brasch, Tobias Herr, John David Jost

Temporal dissipative solitons in a continuous-wave laser-driven nonlinear optical microresonator were observed. The solitons were generated spontaneously when the laser frequency was tuned through the effective zero detuning point of a high-Q resonance, wh ...
