“…Under the action of the laser pulse, a tiny amount of the film material is transferred from the support to the flat substrate, which is placed parallel and at a short distance to the former one. Although LIFT was initially developed to deposit patterns of metals, 3 its use was quickly extended to other inorganic materials 4 and, more recently, to pastes and liquids. 5 The possibility of transferring liquids through LIFT revealed that this technique could be applied to the deposition of organic and biological materials in solution, since the liquid solvent would act simultaneously as energy absorber and transport vector of the molecules.…”

A functional DNAmicroarray was prepared through the laser-induced forward transfer (LIFT) technique. In a first experiment, droplets of a buffer solution were spotted onto a substrate at different laser pulse energies. This allowed one to determine that uniform spots with a diameter as small as 40μm could be obtained. In a second experiment, a microarray containing two different human cDNAs and a negative control was spotted through LIFT and submitted to a hybridization assay. The obtained results demonstrated the full functionality of the microarray, which allowed us to prove the viability of LIFT for the production of DNAmicroarrays.Postprint (published version

The authors present the deposition of nanoscale droplets of Cr using femtosecond Ti:sapphire laser-induced forward transfer. Deposits around 300 nm in diameter, significantly smaller than any previously reported, are obtained from a 30 nm thick source film. Deposit size, morphology, and adhesion to a receiver substrate as functions of applied laser fluence are investigated. The authors show that deposits can be obtained from previously irradiated areas of the source material film with negligible loss of deposition quality, allowing subspot size period microarrays to be produced without the need to move the source film. © 2006 American Institute of Physics. ͓DOI: 10.1063/1.2386921͔The laser-induced forward transfer ͑LIFT͒ technique exists as a method for the direct writing of a wide variety of materials with a minimum achievable resolution around 1 m. 1 It is of particular interest due to the ability to pattern material in air and at room temperature onto virtually any substrate. 2 In recent years, significant study has been directed towards extending the range of materials that can be deposited using LIFT; metals, 3 oxides, 2 superconductors, 4 DNA, 5 proteins, 6 fungal spores, 7 polycrystalline Si, 8 and various important electronic and sensing materials 9 have all been transferred. In contrast, efforts to reduce the minimum achievable deposition dimensions have received comparatively little attention. LIFT using nanosecond pulsed lasers ͑ns-LIFT͒ typically produces depositions which at best reproduce the shape and size of the laser focal spot. 10 Femtosecond-LIFT ͑fs-LIFT͒ using an UV excimer laser has been shown to be capable of subspot size depositions with diameters around 0.5 m. 3 Recently, it was demonstrated that ns-LIFT could also be used to produce subspot size deposits by carefully controlling the laser fluence just above the threshold for material transfer. 11 In LIFT, a thin film of the material to be deposited ͑the "source film"͒ is coated onto one face of a transparent substrate ͑the "carrier"͒ and brought into close contact with another substrate ͑the "receiver"͒. A single laser pulse is then focused through the carrier onto the carrier-film interface, where it is absorbed in a shallow layer of the film ͓Fig. 1͑a͔͒. Conventionally, LIFT then occurs by vaporization of film material at the constrained interface, with the resultant pressure buildup propelling film material to the receiver. However, this is the case only for thicker films and high laser fluence; for thin films and fluence just above the threshold for material transfer, it is possible for LIFT to occur solely by melt-through of the source film ͓Fig. 1͑b͔͒. With precise control of the laser fluence, only the center of the melt front reaches the free surface of the film ͓Fig. 1͑c͔͒, allowing molten material under pressure to expand through an unconstrained, subspot size region. With ns-LIFT this process has been shown to facilitate sublaser spot size printing. 11 In this letter we demonstrate that the same process can occur with fs-LIFT...

“…Laser-induced forward transfer (commonly abbreviated to LIFT) is a direct-write technique that allows the selective transfer of many materials on a micrometer scale [1][2][3][4][5], including liquids [6] and living cells [7,8]. In the LIFT process, a thin film serves as a donor material that is to be transferred, which is referred to as the donor layer, see Fig.…”

Solid-phase laser-induced forward transfer of variable shapes using a liquid-crystal spatial light modulator

et al. 2015

Laser-induced forward transfer is a promising method for 3D printing of various materials, including metals. The ejection mechanism is complex and depends strongly on the experimental parameters, such as laser fluence and donor layer thickness. However, the process can be categorized by the physical condition of the ejected material, i.e., the donor layer is transferred in liquid phase or the material is transferred as a 'pellet' in solid phase. Currently, solid-phase transfer faces several problems. Large shearing forces, occurring at the pellet perimeter during transfer, limit the similarity between the desired pellet shape and the deposited pellet shape. Furthermore, the deposited pellet may be surrounded by debris particles formed by undesired transferred donor material. This work introduces a novel approach for laser-induced forward transfer of variable shaped solid-phase pellets. A liquidcrystal spatial light modulator (SLM) is used to apply grayscale intensity modulation to an incident laser beam to shape the intensity profile. Optimized beams consist of a high fluence perimeter around an interior characterized by a lower fluence level. These beams are used successfully to transfer solid-phase pellets out of a 100-nm Au donor layer using a single laser pulse. The flexibility of the SLM allows a variable desired pellet shape. The shapes of the resulting deposited pellets show a high degree of similarity to the desired shapes. Debris-free deposited pellets are achieved by pre-machining the donor layer, prior to the transfer, using a double-pulse process.
