“Supercontinuum sources in emerging wavelength regimes for biomedical applications”

My aim in this theoretical group is to make experimentally simple proof of concepts to prove our theories and the posterior analysis of the measurements comparing them with analytic solutions and numerical calculations.I have studied the properties and the behaviour of magnetic materials and superconductors as well as some of their theories. I learned to do numerical calculations with COMSOL Multiphysics. I successfully performed simple experiments using different types of power supplies, Hall probes, oscilloscopes, small electronic circuits, meta-materials and imagination to design supports and structures.http://grupsderecerca.uab.cat/superconductivity/

High performance mass spectrometry using a quantum sensor.Department of Atomic, Molecular and Nuclear Physics.The objective of this experimental work is to design a quantum sensor based on an ion trap to develop high-performance mass spectroscopyExperimental equipment: Manage different single mode diode lasers, Ti: Sapphire CW laser and control them with different software, design with Autocad and build pieces to try new experiments and new ideas. I have designed different pieces to have inside Paul trap laser light in different directions and I have designed the optical system of a Paul trap and a two sensor Penning trap. Alignment of optical systems using, mirrors, lenses, monomode and multimode fibers, fiber couplers, polarizers, filters, beam splitters, CCD camera, etc. Different measurements with Paul and Penning traps. Maintenance of Penning trap semiconductor with Helium and Nitrogen. Manage of cryocooler and vacuum pumps.I got more experience in how to move and work in a laboratory (making different setups, managing and calibrating different kind of lasers with its softwares, design of vacuum pieces, doing measurments of an ion traps with different cameras and softwares, etc.) and how to look for materials and contact with different commercial companies.

Characterization of ultra-short pulses by nonlinear effects of light (consists of theoretical and experimental parts). Group of nonlinear optics (DONLL) of the Polytechnic University of Catalonia, Department of Nuclear Physics.Experimental equipment: femtosecond pulsed laser (Ti: Sapphire Mira Optima 900-F, Coherent, Verdi-V10 laser pumped Self-Modelocking tunable between 700 and 980 nm, frequency of 76 MHz, 1.8W pulsed mode, 2.3W continuous mode). Study about pulse characterization using several methods (autocorrelation, FROG, SPIDER, d-scan), mainly a new method using the nonlinear crystal SBN. Alignment of optical systems using nonlinear crystals (BBO and SBN), lenses, mirrors, beam splitters, filters, objectives, CCD camera, spectrometer, oscilloscope, Avasoft 7.3, etc. Theoretical study about the evolution of ultra-short pulses characteristics propagating in a crystal, simulations of these propagations and algorithms to analyze the data from the new assembly made with Matlab.
