“…The major advantage of self-healing beams is that they can be used through turbulent media [152] and that they are ideal candidates for particle manipulation at different planes [156,157] and in microscopy [158]. The CR phenomenon has been also reported as an efficient tool to generate Bessel beams [62,159,160].…”

A mis padres, hermanos, sobrinos y a Raquel AcknowledgmentsTot té un principi i un final i aquest serà el punt final a una etapa de la meva vida la qual estic segur que d'aquí uns anys, quan miri enrere, veuré que ha estat probablement la que ha tingut una major rellevància tant a nivell personal com científic. Quan vaig acabar la carrera no tenia gaire clar quin camí seguir però vaig tenir la sort de parlar amb qui ha estat el meu director de tesi, el Jordi, qui em va guiar i va posar tota la seva confiança en mi des del primer moment. Em va oferir un tema original i es va aventurar a dirigir una tesi amb una forta vessant experimental, tot un atreviment venint d'un teòric! Quan vaig començar el Màster, si m'haguessin dit on he arribat 5 anys després mai m'ho hauria cregut i, Jordi, tu tens gran part de culpa de tot això. Moltes gràcies per haver confiat en mi des del primer dia, per haver-te mostrat sempre tan orgullós de tot el que he fet, per haver estat sempre disponible i per ajudar-me i animar-me quan he passat moments durs durant aquest anys. M'has ensenyat a ser un bon científic, a moure'm dins aquest món, a creure em mi i a ser una millor persona. Mai t'estaré prou agraït per tot això i per haver sigut tan proper amb els teus cotilleos, converses de futbol, política, noies, etc. dinant al bar. Has estat com un pare per a mi (bueno, un germà gran, que tampoc ets tan vell per a ser Mompare :P). Si el Jordi ha estat el meu pare en la ciència, el Yury ha estat el meu gurú científic. Mai he trobat una persona tan pacient, que sàpiga tant de qualsevol tema i amb tanta dedicació com tu. M'has ensenyat a ser riguròs, a tenir un mètode, la importància de estar al dia de tot el que es fa en el cap d'estudi, a programar, i un llarg etcètera. En resum, m'has ajudat a donar-me forma a mi mateix com a científic i a tenir perseverança en el que faig. Tot això sense oblidar que per a mi ets un gran amic! Seguidament, també he donar les gràcies al Todor, una de les persones més enèrgiques que conec i amb més passió per la ciència. Tu vas iniciar tot el tema de la refracció cònica al nostre grup i has demostrat que ets realment qui més coneix de cristalls i del fenomen en si. Si no hagués estat per tu, no podríem haver començat res d'això i no podríem haver explotat el fenomen ni una quarta part del que hem fet. Ets un exemple per tenir sempre un somriure a la cara i per aquesta iii iv força que et fa tirar endavant tots els teus projectes. També vull donar les gràcies a altres companys del Grup d'Òptica, començant per la Verònica, que va passar de ser una "professora de la carrera" a ser el meu ideal de constància i l'esforç. Ets un exemple professional a més a més d'una persona molt més propera i alegra del que pot semblar a primera vista. A Ramón también le tengo que agradecer su ayuda y su disponibilidad a lo largo de estos años, su paciencia cuando ha tenido que soportar mis imitaciones y su alegría y naturalidad en todo momento. Amb el Francesc també he compartit molts bons moments, sobretot a les diverses activit...

“…Non-diffractive pump fields have been utilized in nonlinear optical processes like parametric down conversion [2,3,4,5,6,7], second [8,9,10,11], third [12], and higher-order harmonic generation [13]. Furthermore, the accuracy of optical tweezers [14,15,16], optical trapping [17,18,19,20,21] and the resolution of medical imaging [22,23] have been enhanced by the implementation of diffraction-free beams.…”

We experimentally analyze a Bessel beam produced with a conical mirror, paying particular attention to its superluminal and diffraction-free properties. We spatially characterized the beam in the radial and on-axis dimensions, and verified that the central peak does not spread over a propagation distance of 73 cm. In addition, we measured the superluminal phase and group velocities of the beam in free space. Both spatial and temporal measurements show good agreement with the theoretical predictions.

“…Despite the ideal nature of BBs (they carry infinite power), they not only have revealed to be a paradigm for understanding wave phenomena, but also have found applications as diverse as in frequency conversion, or in atom trapping and alignment [7]. Of particular interest for us is the finding [8] that the BB is describable in terms of the interference of two conical Hankel beams [5], carrying equal amounts of energy towards and outwards the beam axis, and yielding no net transversal energy flux in the BB.…”

Nonlinear Unbalanced Bessel Beams: Stationary Conical Waves Supported by Nonlinear Losses

et al. 2004

Nonlinear losses accompanying self-focusing substantially impacts the dynamic balance of diffraction and nonlinearity, permitting the existence of localized and stationary solutions of the 2D+1 nonlinear Schrödinger equation which are stable against radial collapse. These are featured by linear, conical tails that continually refill the nonlinear, central spot. An experiment shows that the discovered solution behaves as strong attractor for the self-focusing dynamics in Kerr media.PACS numbers: 42.65. Re, 42.65.Tg One of the main goals of modern nonlinear wave physics is the achievement of wave localization, stationarity and stability. While in a one-dimensional geometry (e.g., in optical fibers), nonlinearity suitably balances linear wave dispersion, leading to the soliton regime, in the multidimensional case, nonlinearity drives waves either to collapse or instability. In self-focusing of optical beams, for instance, many stabilizing mechanisms, such as Kerr saturation, plasma-induced defocusing, or stimulated Raman scattering, have been explored, and are being the subject of intense debate, mainly in the context of light filamentation in air or condensed matter [1]. These mechanisms, however, are either intrinsically lossy, or, due to the huge intensities involved, are accompanied by losses, which lead ultimately to the termination of any soliton regime. Similar pictures can be traced in all phenomena commonly discussed in the context of the nonlinear Schrödinger equation (NLSE), as Bose-Einstein condensates (BEC) or Langmuir waves in plasma [2]. Nonlinear losses (NLL) arise in BEC from two-and three-body inelastic recombination, and as the natural mechanism for energy dissipation in Langmuir turbulence [3].The question then arises of whether any stationary and localized (SL) wave propagation is possible in the presence of NLL. The response, as shown in this Letter, is affirmative. These SL waves cannot be ascribed to the class of solitary waves, but are instead nonlinear conical waves (as the non-linear X waves [4]) of dissipative type, whose stationarity is sustained by a continuous refilling of the nonlinearly absorbed central spot with the energy supplied by linear, conical tails. These waves are not only robust against NLL, but find their stabilizing mechanism against perturbations in NLL themselves.Among the linear conical waves [5], the simplest one is the monochromatic Bessel beam (BB) [6], made of a superposition of plane waves whose wave vectors are evenly distributed over the surface of a cone, resulting in a nondiffracting transversal Bessel profile. Despite the ideal nature of BBs (they carry infinite power), they not only have revealed to be a paradigm for understanding wave phenomena, but also have found applications as diverse as in frequency conversion, or in atom trapping and alignment [7]. Of particular interest for us is the finding [8] that the BB is describable in terms of the interference of two conical Hankel beams [5], carrying equal amounts of energy towards and outwards the beam ...
