“…The power ratio for two branches is controlled by changing the ellipticity of the input beams' polarization, similarly to a polarization diffraction grating [22]. The dual Airy beam was described theoretically before and was claimed to have better self-regeneration properties [24]. Additionally, in our case, two branches of the beam are orthogonally polarized.…”

We demonstrate a technique to generate accelerating Airy beams with a femtosecond laser-imprinted space variant birefringent structure in silica glass. Our approach enables the generation of dual Airy beams with polarization sensitive beam deflection. The produced beam is used for the glass scribing. After the glass-breaking process, a spontaneous self-detachment of a fiber-like structure occurs that can be exploited as an alternative way for fabricating glass cantilevers.

The first experimental demonstration of finite-energy optical Airy beams was demonstrated by Siviloglou et al. [1]. The envelope of such beams is described by an Airy function. The most interesting attribute of Airy beams is their ability to freely accelerate in the transverse direction during propagation even in the absence of any external potential. These beams were shown to be useful for optical micro-manipulation of small particles and the generation of curved plasma channels. Also they are unique since they are the only nonspreading solutions in one dimension [1].Angular Fourier spectrum of an exponentially truncated Airy function is a Gaussian beam modulated with a cubic phase. In this context, in order to generate Airy beams, the cubic phase has to be imprinted on a Gaussian beam and Fourier transform has to be applied by using a lens. Usually, the cubic phase modulation in an optical beam is created by means of liquid crystal spatial light modulators (SLMs). However, this method requires complicated and expensive setup, which additionally puts a limitation on the input laser power. We present a simple and effective way of generating Airy beams by exploiting femtosecond laser induced nanogratings in fused silica glass. The nanogratings are responsible for the laser induced birefringence and can be employed for controlling both the spatial distribution of the light polarization and the phase in a laser beam [2]. If the laser induced retardance has a value of half wave, by controlling orientation of slow axis angle in the structure, we can manipulate polarization direction of incident linearly polarized light [3]. If incident light is circularly polarized, the phase of the transmitted light will depend on the slow axis angle [4]. Fig. 1. Microscopic image of structure between cross-polarizers (a) and quantitative birefringence microscopy image (b), where pseudocolor represents slow axis angle. Structure size is 2×2 mm. Profiles of generated Airy beam in different distances (c). In the first and second column Airy beams are generated from the incident beams of left-and right-handed circular polarization while the third column shows a dual Airy beam which was generated from linear polarization.To write the Airy beam converter, regeneratively amplified, mode-locked Yb:KGW based femtosecond laser system (Pharos, Light Conversion Ltd.) operating at 1030 nm and delivering pulses of 270 fs (stretched to 800 fs) at 200 kHz repetition rate was utilized. The pulse energy was set to 0.75 J. The light beam was focused via a ×10 (0.16 NA) aspheric lens into a fused silica plate 300 μm below the surface. The control of the incident beam polarization azimuth was performed with an achromatic half-wave plate mounted into a motorized rotation stage. The sample was placed onto a three-dimensional translation stage. Structure of 2×2 mm size was fabricated at 2 mm/s speed. Nanogratings written under these conditions induce retardance of ~266 nm, which corresponds to half wave for 532 nm wavelength.

“…Since Berry and Balazs illuminated this strange characteristic of the Airy wave packet in quantum mechanics [1], interest in Airy beams has steadily increased [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18].…”

To generate finite-power Airy beams, a novel holographic method is proposed. We record the interference pattern between an Airy beam (signal beam) and plane wave (reference beam) on a photopolymer, then decode the hologram by illuminating with the reference beam. The reconstructed beams still present the non-diffraction, acceleration, and self-healing features of optical Airy beams. In addition, angular multiplexing of two Airy beams with opposite acceleration directions is presented.
