Two-photon imaging and selective laser ablation of Cochlea hair cells through a multimode fiber probe

Demetri Psaltis, Christophe Moser, Damien Claude-Marie Loterie, Eirini Kakkava, Marilisa Romito

We demonstrate multimode fiber probe that accomodates dual modality properties for high power ultrashort pulse delivery. A commercially available multimode graded-index (GRIN) fiber is used for two-photon imaging and/or femtosecond laser ablation of Cochle ...

Integrated Si3N4 Soliton Microcomb Driven by a Compact Ultra-low-noise Laser

Tobias Kippenberg, Junqiu Liu, Rui Ning Wang, Erwan Guillaume Albert Lucas, Arslan Sajid Raja, Jijun He, Nicolas Volet, Romain Dany Bruno Bouchand

We generate 100-GHz soliton microcombs in a photonic integrated high-Q Si3N4 microresonator using an ultra-compact, high-power and low-frequency-noise semiconductor-based laser. The soliton is initiated via direct current tuning of the laser. (C) 2019 The ...

Selective femtosecond laser ablation via two-photon fluorescence imaging through a multimode fiber

Demetri Psaltis, Christophe Moser, Damien Claude-Marie Loterie, Eirini Kakkava, Marilisa Romito, Donald Benjaman Conkey

We demonstrate the ability of a multimode fiber probe to provide two-photon fluorescence (TPF) imaging feedback that guides the femtosecond laser ablation (FLA) in biological samples for highly selective modifications. We implement the system through the p ...

Floquet dynamics in the quantum measurement of mechanical motion

Tobias Kippenberg, Liu Qiu, Itay Shomroni, Nicolas Piro Mastracchio, Marie Adrienne Ioannou

The radiation-pressure interaction between one or more laser fields and a mechanical oscillator gives rise to a wide range of phenomena: From sideband cooling and backaction-evading measurements to ponderomotive and mechanical squeezing to entanglement and ...

Thermally stable access to microresonator solitons via slow pump modulation

Tobias Kippenberg, Junqiu Liu, Victor Brasch, Tobias Herr

Temporal dissipative Kerr solitons (DKSs) in microresonators provide ultra-short optical pulses and low-noise frequency combs with gigahertz to terahertz repetition rates. Owing to their unique properties, they have found application in fields, including o ...

Local tuning of fused silica thermal expansion coefficient using femtosecond laser

Yves Bellouard, Pieter Vlugter, Erica Kathleen Block

Femtosecond laser exposure of fused silica in the nonablative regime can lead to various localized bulk modifications of the material structure. In this paper, we show that these laser-induced modifications can be used to tune silica thermal expansion prop ...

Development and performance evaluation of a high mass resolution time of flight laser ablation ionisation mass spectrometer

Reto Wiesendanger

This thesis contributes to the field of analytical chemistry of solid samples by introducing a new instrument with unprecedented performance characteristics and analytical capabilities. The instrument is based on the laser ablation and ionisation time-of-f ...

ULTRASTABLE LASER SYSTEM FOR SPECTROSCOPY OF THE 1.14 mu m INNER-SHELL CLOCK TRANSITION IN Tm AND ITS ABSOLUTE FREQUENCY MEASUREMENT

Sergey Fedorov

We characterize a 1.14 mu m ultrastable semiconductor laser system for precision spectroscopy of Tm inner-shell clock transition using a frequency comb. We stabilize both the repetition and the carrier-envelope offset frequencies of a commercial Ti : sapph ...

In Situ Observation of Coulomb Fission of Individual Plasmonic Nanoparticles

Marcel Drabbels, Ulrich Lorenz, Pavel Olshin, Jonathan Mark Voss, Romain Loïc Charbonnier

Reshaping plasmonic nanoparticles with laser pulses has been extensively researched as a tool for tuning their properties. However, in the absence of direct observations of the processes involved, important mechanistic details have remained elusive. Here, ...

SCALAR: Simultaneous Calibration of 2-D Laser and Robot Kinematic Parameters Using Planarity and Distance Constraints

Teguh Santoso Lembono

In this paper, we propose SCALAR, a calibration method to simultaneously calibrate the kinematic parameters of a 6-DoF robot and the extrinsic parameters of a 2-D laser range finder (LRF) attached to the robot's flange. The calibration setup requires only ...

Semiconductor-based narrow-line and high-brilliance 193-nm laser system for industrial applications

Toralf Scharf, Wilfried Noell, Raoul Kirner, Xiaolong Wang

We present a novel industrial-grade prototype version of a continuous-wave 193 nm laser system entirely based on solid state pump laser technology. Deep-ultraviolet emission is realized by frequency-quadrupling an amplified diode laser and up to 20 mW of o ...
