Abstract:

This paper discusses a device for implementing the well-known principle of canalization of laser radiation into a thin laminar liquid jet (a beamguide) that serves as a medium for delivering radiation to an object and a cooling medium. A stable laminar liquid jet with a fairly large diameter of 0.3–0.8 mm is used at a flow velocity of about 10 m/s, along with a new principle by which laser radiation is directly introduced into the jet from a quartz optical fiber into the liquid beamguide. As a result, the input device can be made simple, compact, flexible, and mobile. With radiation power of up to 4 W delivered along the jet, it was demonstrated that it is possible to fine-process sheet polystyrene, as well as to dissect models of hematopoietic biological tissues with no scorching or carbonization of the seam or the adjacent regions.
