In-Volume Glass Modification Using a Femtosecond Laser: Comparison Between Repetitive Single-Pulse, MHz Burst, and GHz Burst Regimes.

In this study, we report, for the first time, to the best of our knowledge, on in-volume glass modifications produced by GHz bursts of femtosecond pulses. We compare three distinct methods of energy deposition in glass, i.e.

Bessel Beam Femtosecond Laser Interaction with Fused Silica Before and After Chemical Etching: Comparison of Single Pulse, MHz-Burst, and GHz-Burst.

We investigate the elongated modifications resulting from a Bessel beam-shaped femtosecond laser in fused silica under three different operation modes, i.e., the single-pulse, MHz-burst, and GHz-burst regimes.

Patients' knowledge about renal secondary effects of anti-tumoral drugs and renal protection measures.

Purpose: Onco-nephrology is an emerging subspecialty aiming to better understand and prevent renal events in cancer patients. We assessed patients' knowledge about (1) oncological/hematological treatments induced renal toxicity and (2) kidney protective measures.

Methods: Adult patients receiving systemic anti-tumor treatments in multiple day hospital units in France answered a self-administered questionnaire about their knowledge and expectations related to treatment-associated renal toxicity.

Kidney involvement in myelodysplastic syndromes.

Introduction: The objective of this study was to describe kidney involvement in patients with myelodysplastic syndromes (MDS), their treatments, and outcomes.

Methods: We conducted a multicenter retrospective study in seven centers, identifying MDS patients with acute kidney injury (AKI), chronic kidney disease (CKD), and urine abnormalities.

Results: Fifteen patients developed a kidney disease 3 months after MDS diagnosis.

Femtosecond Laser Percussion Drilling of Silicon Using Repetitive Single Pulse, MHz-, and GHz-Burst Regimes.

In this contribution, we present novel results on top-down drilling in silicon, the most important semiconductor material, focusing specifically on the influence of the laser parameters. We compare the holes obtained with repetitive single pulses, as well as in different MHz- and GHz-burst regimes. The deepest holes were obtained in GHz-burst mode, where we achieved holes of almost 1 mm depth and 35 µm diameter, which corresponds to an aspect ratio of 27, which is higher than the ones reported so far in the literature, to the best of our knowledge.
