Abstract
Prototype of YLF: Er diode-pumped micro laser was developed. Influence features of the developed micro laser prototype radiation with a wavelength of 2. 84 μm on hard tissues of human tooth were examined. Effects of turning white, carbonization and ablation of dental hard tissues as a result of laser exposure were found. Thresholds of these effects were identified. It was established that the micro hardness of human dentin can be increased by more than 20% as a result of repeated exposure of laser pulses with energy lower than the turningwhite threshold.
