The present invention relates to an optical fiber and a device including the optical fiber. The optical fiber is an optical fiber () functionalized with at least one particle () of a polymeric gel comprising at least one photosensitive molecule () and at least one biomolecule (), wherein the at least one particle () of the polymeric gel is covalently bound to said optical fiber ().

Optical fiber and device for releasing molecules

A guiding system () for guiding the insertion of a needle () and a catheter () for medical use in a biological tissue, the guiding system () comprising: &#x2014;the needle () &#x2014;the catheter () inserted into the needle (); &#x2014;an optical fiber () provided with at least one optical sensor () and inserted into the catheter (), &#x2014;a first blocking device () for firmly blocking the catheter () inside the needle ().

The performance of free electron lasers can be greatly enhanced by including a non-linear optical element within the resonator for the oscillator. A system is described to enhance the peak or average power output of the FEL oscillator, or to modify the time structure of the oscillator output through the use of a non-linear element which modulates or diverts a portion of the optical wave circulating in the resonator.

Non-linear intractivity optical devices for free electron lasers

A technique for the simultaneous measurement, in real time, of the changes in mode size, pulse length, and power of a wavetrain of laser pulses delivered by mode-locked or other pulsed laser systems contemplates directing respective portions of the beam along each of three beam paths. The beam portions along the first and second beam paths are subjected to respective, and different, degrees of focusing, and then passed through respective non-linear elements which generate radiation at the second harmonic. The first harmonic components are removed, and the second harmonic components are passed to respective first and second detectors which generate signals representative of the total second harmonic energy along each of the first and second beam paths. The beam portion along the third beam path is passed to a detector which generates a signal representative of the total energy in the beam pulse. The three signals are combined to give values proportional to peak power, pulse length, and mode size.
