UV laser direct writing of ferroelectric domain inverted structures in single crystal lithium niobate
No full textFerroelectric domain engineering in lithium niobate (LN) is a subject of extensive research mainly for the fabrication of quasi-phase-matched (QPM) nonlinear optical devices but also for the improvement of linear devices and microstructuring. The most common method for ferroelectric domain engineering is by the application of an external electric field, higher than the coercive field (E Here we present UV laser induced inhibition of ferroelectric domain inversion where spatially selective preexposure of the +z face of congruent LN samples inhibits domain inversion in this area upon the application of an external electric field. In these experiments the two steps of i) UV illumination and ii) E-field application are separated; the application of the external electric field can take place long after (days-months) after the UV illumination

High resolution single-pulse multiphoton polymerisation using a digital multimirror device
No full textThere is considerable interest in the use of digital multimirror devices (DMDs) for laser-based machining, and recent work has demonstrated step-and-repeat ablation patterning with ~400nm writing resolution, with proposed applications in photonics and the medical sciences. DMD-based laser-machining can be a high resolution (sub-micron), rapid (1cm by 1cm per hour is predicted) and flexible technique that is proposed to offer an alternative approach to existing focussed ion beam and lithography-based fabrication, which while offering higher resolution are considerably slower

Low-loss Ti:sapphire waveguides fabricated by pulsed laser deposition
No full textWe report the fabrication and characterisation of Ti:sapphire films epitaxially grown on c-cut sapphire substrates by pulsed laser deposition (PLD). Deposition conditions have been studied extensively and optimised in order to produce high-performance optical waveguides. In particular we have studied the effects of different values of oxygen pressure, background gases and substrate temperature on the resultant surface roughness, composition, crystallinity, fluorescence and waveguide losses. For instance we found that Ti:sapphire films deposited in Ar feature higher fluorescence than those grown in O2 and N2 (see Figure 1) under the same deposition conditions: laser fluence F ~ 3.3 J/cm2, laser repetition rate f = 20 Hz, substrate temperature T ~ 1050°C, gas pressure P ~ 2.10-3 mbar, target-substrate distance d = 4 cm
Diode-pumped garnet crystal waveguide structures fabricated by pulsed laser deposition
