Laser-induced Hertzian fractures in silica initiated by metal micro-particles on the exit surface.

Optics express

Feigenbaum E, Raman RN, Cross D, Carr CW, Matthews MJ.
PMID: 27409875
Opt Express. 2016 May 16;24(10):10527-36. doi: 10.1364/OE.24.010527.

Laser-induced Hertzian fractures on the exit surface of silica glass are found to result from metal surface-bound micro particles. Two types of metal micro-spheres are studied (stainless-steel and Al) using ultraviolet laser light. The fracture initiation probability curve as...

Cross D, Jeanmonod R.
PMID: 25883822
Case Rep Otolaryngol. 2015;2015:460208. doi: 10.1155/2015/460208. Epub 2015 Mar 26.

It is estimated that more than 60% of people have epistaxis in their lifetimes, and as such it is a common complaint encountered in emergency medicine. Although epistaxis is usually self-limited and benign, it can occasionally be a sign...

Gain dynamics in quickly ionized plasma for seeded operated soft x-ray lasers.

Optics letters

Guilbaud O, Cojocaru GV, Li L, Delmas O, Ungureanu RG, Banici RA, Kazamias S, Cassou K, Neveu O, Demailly J, Baynard E, Pittman M, Le Marec A, Klisnick A, Zeitoun P, Ursescu D, Ros D.

Opt Lett. 2015 Oct 15;40(20):4775-8. doi: 10.1364/OL.40.004775.

Harmonic seeded operation of a neon-like titanium plasma-based soft x-ray laser is described. The plasma amplifier is pumped with a variation of the grazing incidence technique involving a fast and localized ionization step. We discuss its effect on gain...

Self-Injection Locking of a Vortex Spin Torque Oscillator by Delayed Feedback.

Scientific reports

Tsunegi S, Grimaldi E, Lebrun R, Kubota H, Jenkins AS, Yakushiji K, Fukushima A, Bortolotti P, Grollier J, Yuasa S, Cros V.
PMID: 27241747
Sci Rep. 2016 May 31;6:26849. doi: 10.1038/srep26849.

The self-synchronization of spin torque oscillators is investigated experimentally by re-injecting its radiofrequency (rf) current after a certain delay time. We demonstrate that the integrated power and spectral linewidth are improved for optimal delays. Moreover by varying the phase...

Origin of spectral purity and tuning sensitivity in a spin transfer vortex nano-oscillator.

Physical review letters

Hamadeh A, Locatelli N, Naletov VV, Lebrun R, de Loubens G, Grollier J, Klein O, Cros V.
PMID: 25014825
Phys Rev Lett. 2014 Jun 27;112(25):257201. doi: 10.1103/PhysRevLett.112.257201. Epub 2014 Jun 25.

We investigate the microwave characteristics of a spin transfer nano-oscillator (STNO) based on coupled vortices as a function of the perpendicular magnetic field H(⊥). Interestingly, we find that our vortex-based oscillator is quasi-isochronous independently of H(⊥) and for a...

Compact, high-Q, zero temperature coefficient, TE011 sapphire-rutile microwave distributed Bragg reflector resonators.

IEEE transactions on ultrasonics, ferroelectrics, and frequency control

Some novel new resonator designs based on the distributed Bragg reflector are presented. The resonators implement a TE011 resonance in a cylindrical sapphire dielectric, which is confined by the addition of rutile and sapphire dielectric reflectors at the end...
