Description
  • Interaction of nanosecond pulsed lasers with material was studied from thermal point of view using experimental techniques and theoretical approach of dimensional analysis. Experimental data of laser heating, melting and plasma formation on metallic samples and silicon, presented mainly in previous publication and partly in this paper, were used for formation of experimental mathematical model in the form of criteria equations. Four different criteria equations were created: for maximum surface temperature increase, melting threshold, melting duration and plasma formation threshold. The criteria equations can be used for approximate prediction of laser pulse effects on materials without creating an exact mathematical or numerical model and for control of technological processes.

  • Působení nanosekundového pulzního laseru na materiál bylo studováno z pohledu tepelných jevů použitím experimentálních technik a teoretického přístupu rozměrové analýzy. Naměřená data laserového ohřevu, tavení a tvorby plazmatu na kovových vzorcích a křemíku, ukázaná převážně v předchozí publikaci a částečně i v této, byla použita pro vytvoření experimentálního matematického modelu ve tvaru kriteriálních rovnic. Byly vytvořeny čtyři kriteriální rovnice: pro maximální vzrůst teploty, práh tavení, dobu existence taveniny a práh tvorby plazmatu. Kriteriální rovnice mohou být použity pro přibližnou předpověď efektů laserového pulzu na materiál bez nutn (cs)
