AB  - Temperature  distribution  induced  by  laser  radiation  is  a  very  important 
parameter for an efficient and safe application of lasers in different ceramic 
processing  techniques.  This  paper  presents  the  results  of  an  infrared 
thermography (IRT) application for monitoring temperature distribution on 
a ceramic surface during Nd: YAG laser irradiation with different fluences 
and 8ns pulse duration. FLIR, E40 and SC7200 IR cameras were used with 
the  aim  of  recording  the  maximum  temperature  in  the  irradiated  zones.  It 
was  expected  that  IRT  could  give  some  information  related  to  the  heat 
affected zone and possible damage to the base material; however, the results 
have  shown  that  IR  cameras,  even  those  with  high  performance  such  as 
SC7200,  cannot  record  the  maximum  temperature  value  at  the  moment  of 
laser  operation,  but  only  the  average  temperature  of  the  bulk  sample 
material  after  laser  pulses.  The  results  of  the  numerical  simulation  have 
confirmed the value of the thermographic measurements. The microstructure 
and  micromorphology  of  the  ceramic  surface  before  and  after  the  laser 
treatment  were  analysed  by  optical  and  scanning  electron  microscopy  as 
well  as  by  examining  the  roughness  of  the  irradiated  and  non-  irradiated 
surfaces,  while  the  micromechanical  changes  were  analysed  by  comparing 
the micro-hardness of the irradiated and non-exposed surfaces.
