We evaluate the design of Q-switched microchip lasers to examine the limit of their scaling to shorter picosecond pulses. A numerical model based on the laser rate equations is developed and used to predict the output characteristics of prospective laser designs. Based on the modeled results, we employ a SESAM as a passive Q-switch and thin crystals of Nd:YVO4 as a gain medium to experimentally demonstrate the production of pulses as short as 22 ps.
