Currently, new technologies for modifying a shape and a color of a material are increasingly used to create art objects. Laser processing is a promising technology in this field, as it allows one to influence a material surface in a completely new way to create an art object on it. For example, due to the laser formation of an oxide film on a metal surface, it is possible to create color images without using paints. The use of an optical system and numerical control of such devices allows one to create high-resolution images (about 500 dpi). However, to create a hand-made art object, it is necessary to have an opportunity for actor to control the movement of the laser beam in the creative process. Focusing on this aspect, a hand-held device "Laser brush" was developed [1].
For the convenience of using the "Laser brush", the device design is implemented on the basis of a continuous fiber laser source. The collimator of such a laser source is enough small in size, because it does not have additional optical components that are present in the collimators of pulsed fiber laser sources. It is worth noting that the formation of oxide films on the surface of titanium by continuous laser radiation has been under-explored.
The report presents the results of testing the convenience of working with the "Laser brush" device. Based on the data obtained, a new device design has been developed. Additionally, software has been developed to teach color management skills before working with a "Laser brush" device. The technological possibilities of erasing and rewriting colors after repeated laser processing, applicable to a continuous laser source, are demonstrated. Previously, these capabilities were presented only for a pulse source [2]. Focusing on a comparative analysis of the functional and technological opportunities of a hand-held device and a stationary laser complex, a new method for creating color images is proposed. This method involves the sharing of devices, which allows you to create expressive art objects.
