The first advance of the results of the Design and Construction of a dye solution Circulator System controlled by means of virtual instrumentation technologies for the construction of the tuneabla laser optical head is presented. The dye solution circulator system is constituted by a container for the dye solution, a hydraulic bomb (dye flow generator), an electro-valve of step (device that allows to regulate the pressure and the feedback of the dye solution, flow), a power source 1 to 24 volts , a cuvette across which the dye solution solution passes to be optically excited by another laser, which will be implemented in the second phase of the research application
Key words: dye solution Circulator System , virtual instrumentation technologies , User Graphic Interface.
