Abstract

A theoretical model on actively Qswitched Nd3+doped quasithreelevel laser including the energy transfer upconversion and the ground state reabsorption is developed The analytical expressions of the fractional thermal loading and the average output power are obtained and the influence of ETU effects on laser performance for different repetition rate is analyzed The average output power and the thermal focal length of the Qswitched 946 nm laser are acquired in experiment The good agreement between the experimental data and theoretical results demonstrates the reliability of the theoretical model
