Spot Size Effect of CW Laser Induced Damage Threshold in Optical Materials
Experimental research shows that laser induced damage thresholds (LIDT) are strongly dependent on the beam radius. The thermo-elastic model describing the interaction of CW laser with uniform optical materials is established, and material response and structure response are studied independently. Study shows that spot size effect in material response results from the energy loss of the irradiated area. As for structure response, different mechanical boundaries result in different relationships of LIDT with radius of laser beam.
