✦ Synopsis

The purpose of the study was to determine the proper laser radiation for ceramic bracket debonding and the investigation of the tooth root temperature injury. The debonding was investigated by diode-pumped continuously running Tm:YAP and Nd:YAG lasers, and by GaAs laser diode generating radiation with the wavelengths 1.997 μm, 1.444 μm, and 0.808 μm, respectively. The possibility of brackets removal by laser radiation was investigated together with the tooth and, it specifically, root temperature rise. From the results it follows that continuously running diode pumped Tm:YAG or Nd:YAG laser generating wavelengths 1.997 μm or 1.444 μm, respectively, having the output power 1 W can be good candidates for ceramic brackets debonding.

Compact broadly tunable Cr:ZnSe laser was constructed and described. Cr:ZnSe bulk crystal was grown by the Bridgman technique. In our best knowledge the bulk Cr:ZnSe prism was utilized as laser active media and simultaneously as an intra-cavity dispersive element for the first time. The maximal outp
