Abstract

Continuous wave 808 nm pump laser-induced thermal damage of polycrystalline transparent ceramic and crystalline Nd:YAG materials was investigated both experimentally and theoretically. The measured temperature agrees well with the theoretical simulation, and the maximum hoop stresses occur on the incident facet of the end-pumped rod at about 2 times of the pump beam radius w 0 , where the temperature gradient is the highest and the damage occurs first at this location. The fracture-limited laser intensity of ceramics was experimentally measured to be 6.4 ± 0.6 kW / cm 2 , nearly 64% higher than that of the crystals ( 3.9 ± 0.3 kW / cm 2 ). The deduced thermal fracture stress for ceramic was 386 ± 50 MPa , which is 64% higher than that of the crystals ( 235 ± 16 MPa ).
