The transient temperature profiles in continuous-wave (cw) end-pumped Q-switched lasers are investigated by solving a numerical model coupling the transient heat conduction equation and the rate equations, in which the influences of the thermal time constant, the fluorescence lifetime and the repetition rate on the temperature variation are considered. Furthermore, the buildup dynamics of thermal...
Thermal effect control is critical to scale the output power of diode end-pumping solid lasers to several watts up and beyond. Diffusion bonding crystal has been demonstrated to be an effective method to relieve the thermal lens for the end-pumping laser crystal. The temperature distribution and thermal lens in Nd:YVO 4 /YVO 4 composite crystal was numerically analyzed and compared...
