All-fiber versatile laser frequency reference at 2μm for CO2 space-borne lidar applications

We present a frequency stabilized laser at 2051 nm based on a versatile all-fibered stabilization setup. A modulation sideband locking technique is implemented to lock the laser at a controlled frequency detuning from the center of the CO2 R(30) transition ...

Self-referenced photonic chip soliton Kerr frequency comb

Tobias Kippenberg, Victor Brasch, Erwan Guillaume Albert Lucas, John David Jost, Michael Wolfgang Geiselmann

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 ...

Detuning-dependent properties and dispersion-induced instabilities of temporal dissipative Kerr solitons in optical microresonators

Tobias Kippenberg, Erwan Guillaume Albert Lucas, John David Jost, Maxim Karpov, Hairun Guo

Temporal-dissipative Kerr solitons are self-localized light pulses sustained in driven nonlinear optical resonators. Their realization in microresonators has enabled compact sources of coherent optical frequency combs as well as the study of dissipative so ...

Chip-scale Optical Resonator Enabled Synthesizer (CORES) Miniature systems for optical frequency synthesis

Nicolas Volet, Tobias Kippenberg, Martin Hubert Peter Pfeiffer, Hairun Guo

An approach for a low-power chip-scale package is described, that provides a laser output with a programmable frequency across 50 nm of bandwidth centered at 1550 nm, and a resolution of one part in 10(14). ...

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

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

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 ...

Characterization and modeling of microstructured chalcogenide fibers for efficient mid-infrared wavelength conversion

Camille Sophie Brès, Adrien Billat, Svyatoslav Kharitonov, Davide Grassani, Sida Xing

We experimentally demonstrate wavelength conversion in the 2 μm region by four-wave mixing in an AsSe and a GeAsSe chalcogenide photonic crystal fibers. A maximum conversion efficiency of −25.4 dB is measured for 112 mW of coupled continuous wave pump in a ...

Quantum state resolved molecular beam reflectivity measurements: CH4 dissociation on Pt(111)

Rainer Beck, Helen Jane Chadwick, Ana Gutiérrez González

The King and Wells molecular beam reflectivity method has been used for a quantum state resolved study of the dissociative chemisorption of CH4 on Pt(111) at several surface temperatures. Initial sticking coefficients were measured for incident CH4 prepare ...

Harmonization of chaos into a soliton in Kerr frequency combs

Tobias Kippenberg

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 ...

Laser-assisted inkjet printing of highly viscous fluids with sub-nozzle resolution

Demetri Psaltis, Christophe Moser, Miguel Antonio Modestino, Paul Delrot

Drop-on-demand inkjet printing is mostly based on thermal and piezo-actuation, allowing for densely packed nozzles in inkjet printers. However, the droplet diameter is typically defined by the nozzle diameter, thus limiting the range of viscosity that can ...

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

Elyahou Kapon, Alexei Sirbu, Vladimir Iakovlev

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 ...
