Stability of continuously pumped pulse-periodic YAG:Nd3+

An investigation is made of the stability of the characteristics of Q-switched radiation from continuously pumped neodymium-doped aluminum garnet lasers operated under stable periodic conditions in systems with Q-switching and cavity dumping. The ranges of stable operation of periodically Q-switched lasers are determined analytically. The dependences of the fluctuations of the maximum pulse power P_m and pulse duration on the pump fluctuations and losses are determined. It is shown that a stability of P_m ~10^–2% is technically feasible.
