Накратко на български
Полупроводниковите лазери се използват за създаване на специални светлинни лъчи (Бесел), които позволяват преместването на микроскопични биологични обекти. Тези компактни и евтини източници на светлина помагат за развитието на биофотониката и създаването на лабораторни системи върху чип.

Semiconductor lasers for generation of non-diffracting (Bessel) beams
The goal of the SENDBEAMS project was the development of compact, low-cost, reliable and highly-efficient semiconductor laser sources of non-diffracting (Bessel) light beams for optical trapping and tweezing and manipulation of micro-machines and micro-fabrication. This new generation of semiconductor lasers has to become an alternative to the conventionally used gas and solid-state lasers, which are more expensive, cumbersome and inefficient. During the project, we successfully demonstrated few-watt power level Bessel beams with the central lobe diameters of a few to tens micrometers generated from semiconductor lasers. To the best of our knowledge, these are the best results for Bessel beams generated from any semiconductor light source to date and are comparable to that achievable from vibronic lasers. We have also developed a method of the 'interference' focusing of the multimode laser diode radiation and demonstrated reduction of the focal spot sise of high-power semiconductor lasers and light-emitting diodes to a level unachievable by means of traditional focusing. The project culminated with the first demonstration of the optical trapping and manipulation of the biological objects with Bessel-beamed semiconductor laser. We believe that the novel laser systems developed during this project are going beyond the current state-of-the-art and will help to consolidate and extend the world-leading position of the European research in this field. Development of compact, low cost and high performance laser sources of non-diffracting beams has high practical significance. It will promote an evolution in different biomedical and science areas, in particular, biophotonics research and lab-on-a-chip applications. Compactness of the Bessel-beamed semiconductor lasers developed will allow ultra-compact setups capable of revolutionising of the filed supported by the low price which will increase their expansion in to different application areas and make clear contribution to establishing European excellence and competitiveness.

Цел на проекта
Propagation of non-diffracting light beams, called Bessel beams, which are capable of retaining their intensity during propagation are particularly important in respect of a number of biophotonics applications such as optical trapping and tweezing, Doppler velocity measurement and manipulation of micro-particles and micro-fabrication. The main goal of this project is to develop compact, low-cost, reliable and highly-efficient all semiconductor based sources of non-diffracting light beams which has to become an alternative to the conventionally used solid-state lasers, which are more expensive, cumbersome and inefficient. Based on our recent results, it is planned to develop non-diffracting light beams from various semiconductor laser sources such as vertical cavity surface-emitting lasers, edge-emitting laser diodes and optically and electrically pumped semiconductor disk lasers with output powers ranging from a few milliwatts to a few Watts and central-lobe diameters of about few micrometers with propagation lengths from a few to tens of millimeters. This will then enable us to propose and implement new concepts and design strategies for reliable low-cost optical tweezers and manipulators suitable for broad use in biomedical laboratories. Our plan is to apply new concepts to the generation of Bessel beams in applications where the quality-to-cost ratio, efficiency and size are especially relevant such as lab-on-a-chip, micro-manipulation and micro-machines applications.
