Abstract Thermal effects are a result of the temperature field and temperature fluctuation. They are an important factor in the design and operation of end-pumped lasers. In this paper, we investigate both the thermal effect and thermally induced diffraction losses. A thermal model is established that can explain the thermal effect in an anisotropic cubic laser crystal that is end-pumped by a laser diode during repeated pulsed operation. By solving the thermal flow equation numerically, the dynamics of the thermal build-up as well as the temperature distribution in the laser crystal were obtained. When the laser crystal reached a quasi-steady state, the thermally induced diffraction losses show oscillatory behaviour, which is inversely proportional to the frequency of the pump pulses and pump power.
