Laser coating of a Zr-based metallic glass on an aluminum substrate

Roland Logé, Stefano Mischler, Jamasp Jhabvala, Alejandro Roda Buch, Navid Sohrabi

Cladding of a Zr-based metallic glass (MG) on an aluminum substrate was conducted using a layer-wise laser additive manufacturing (AM) method, leading to relative densities higher than 99%. The thickness of the cladding was about 300 μm. The effect of lase ...

Bistable Puncturing Tool for Retinal Vein Cannulation

Yves Bellouard, Simon Nessim Henein, Charles Baur, Lisa Anaïs Jeanne Bonnefoy

An innovative surgical tool prototype dedicated to safe puncturing has been developed for the treatment of retinal vein occlusions (RVOs). The tool is manufactured monolithically by femtolaser printing in fused silica. It consists of a programmable bistabl ...

Photocontrolled release of the anticancer drug chlorambucil with caged harmonic nanoparticles

Sandrine Gerber, Jean-Pierre Wolf, Jérémy Vuilleumier, Raphaël Jovita De Matos, Luigi Bonacina

While chemotherapy is one of the most used treatments in oncology, the systemic administration of chemotherapeutics generally results in undesired damages to healthy tissues and cells, side effects such as severe nausea and leukopenia, and reduced efficacy ...

Flexure Pivot Oscillator With Intrinsically Tuned Isochronism

Simon Nessim Henein, Ilan Vardi, Etienne Frédéric Gabriel Thalmann, Mohammad Hussein Kahrobaiyan

The most important property for accurate mechanical time bases is isochronism: the independence of period from oscillation amplitude. This paper develops a new concept in isochronism adjustment for flexure-based watch oscillators. Flexure pivot oscillators ...

An effective rule for translating optimal selective laser melting processing parameters from one material to another

Roland Logé, Jamasp Jhabvala, Eric Boillat, Rita Drissi Daoudi, Hossein Ghasemi Tabasi, Toni Ivas

Selective Laser Melting (SLM) or Laser Powder Bed Fusion (L-PBF) is the most studied laser-based additive manufacturing process for metals and alloys. One important issue in SLM is the time-consuming identification of a process window leading to quasi full ...

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

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

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 ...

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 ...

Imaging hair cells through laser-ablated cochlear bone

Demetri Psaltis, Ye Pu, Marilisa Romito

We report an innovative technique for the visualization of cells through an overlying scattering medium by combining femtosecond laser bone ablation and two-photon excitation fluorescence (TPEF) microscopy. We demonstrate the technique by imaging hair cell ...
