The paper discusses the problem of limitations on using the powerful lasers in industry due to low laser power efficiency. It considers a combination of some thermal sources as a multiplier of the process. The object of the research is a hybrid laser thermal source.The authors estimate the efficiency by calculating the impact of hybrid processing parameters on the laser output power. The computer model created by the researchers from BMSTU and SPbSTU is used. The paper introduces a prediction model of the process efficiency developed on the basis of the regression analysis approach. Both the processing speed and the distance between the thermal sources are considered varied factors while the laser power efficiency is thought to be a response. The developed nonlinear mathematical model of dependence of the laser power efficiency on operating parameters during the hybrid laser process of hardening steel proves to be highly precise in predicting the results.
