A new technique of the controlled laser mass transfer

3. Development and research of a new technique of the controlled laser mass transfer (polymers, dielectrics, dyes, metal films, liquids, etc..) from the transparent, for laser radiation, donor medium to the specified object.

The idea and purpose of new laser technology is that a pressure pulse, which occurs at laser radiation focusing at the interface of transparent donor medium and a portable material, carries out the mass transfer. A direct laser printing allows you to transfer materials from the carrier to the substrate directly, without intermediate operations, in a mode providing the formation of the desired structure. It is important that the mass transfer is performed without violating the physical-chemical properties of the materials.
The aim of the work is a significant improvement of power and speed characteristics of the process through the analysis of current physical processes and the application of new technical solutions, such as a spatial modulation of laser radiation with subsequent application of the optical amplifier. Possibility of using a direct laser printing technology in the production of microelectronics components, in the printing industry to create a high-speed colour laser printing devices, including the oil painting, in medicine in the field of tissue engineering and in biotechnology for biochips production determines a magnitude of the research.

A possibility of creating the oil painting printer [3] has been demonstrated. This printer can be used to copy the World Art masterpieces. The research started in 2000. Two patents of the Russian Federation for method and device [1, 2] protect the Priority. At the microscopic level the DLT devices, using a power and highly informative laser beam, allow to produce such operations as: a mass transfer with a given configuration; creation of multilayer objects; annealing; melting; micro processing and laser alloying. A possibility of laser printer creating, printing with viscous inks including oil ones [1-4], has been demonstrated experimentally. The scheme of experimental facility is shown in Fig. 6. At present a possibility of DLT method applying in Medicine is under examination.
