“…The ridge structures for light confinement in the lateral direction were fabricated by fs-laser structuring [11] with a multiplexed writing laser beam. To obtain the rib structures, two parallel channels were micromachined by fs-laser ablation on the surface of the planar waveguides.…”

“…The fs-laser ablation is used to remove the selected parts of the planar waveguide surface, constructing thus the ridges. In crystals, type-IV ridge waveguides have been demonstrated in several systems, such as -BaB 2 O 4 [6], Nd:YAG [7], Nd:GGG [8], Nd:GdCOB [9], TiO 2 [10], or (Yb,Nb):RTP/RTP [11], achieving applications as waveguide lasers or frequency converters. This technology does not require the use of clean room facilities, and allows rapid prototyping because it is a mask-less technology.…”

Ridge waveguide laser in Nd:LiNbO3 by Zn-diffusion and femtosecond-laser structuring

Ridge waveguide lasers have been fabricated on Nd 3+ doped LiNbO 3 crystals. The fs-laser writing technique was used to define ridge structures on a gradient-index planar waveguide fabricated by Zn-diffusion. This planar waveguide was formed in a z-cut LiNbO 3 substrate homogeneously doped with a 0.23% of Nd 3+ ions. To obtain lateral light confinement, the surface was then micromachined using a multiplexed femtosecond laser writing beam, forming the ridge structures. By butting two mirrors at the channel waveguide end-facets, forming a waveguide laser cavity, TM-polarized laser action at 1085 nm was achieved by end-fire TM-pumping at 815 nm. The waveguide laser shows a threshold of 31 mW, with a 7% of slope efficiency.

“…Besides, it does not require a clean room processing to be carried out. Using this technique, low loss waveguides have been fabricated in different types of materials such as glasses or dielectric crystals [4,5]. Recently, active devices, such as waveguide lasers, fabricated with this technique, have been also reported [6].…”

“…In addition, holographic femtosecond laser processing assisted by a spatial light modulator (SLM) can be also regarded as a dynamic method for arbitrary irradiance patterning. Note that micro-structured surfaces could be useful i.e., for the fabrication of microfluidic devices [17] or integrated photonics [18].…”

We experimentally demonstrate multi-beam high spatial resolution laser micromachining with femtosecond pulses. The effects of chromatic aberrations as well as pulse stretching on the material processed due to diffraction were significantly mitigated by using a suited dispersion compensated module (DCM). This permits to increase the area of processing in a factor 3 in comparison with a conventional setup. Specifically, 52 blind holes have been drilled simultaneously onto a stainless steel sample with a 30 fs laser pulse in a parallel processing configuration.
