We present passively Q-switched microchip lasers with items bonded by spin-on-glass glue. Passive Q-switching is obtained by a semiconductor saturable absorber mirror. The laser medium is a $\mathrm{Nd}:\mathrm{Y}\mathrm{V}{\mathrm{O}}_4$ crystal. These lasers generate pulse peak powers up to $20\mathrm{kW}$ at a pulse duration as short as $50\mathrm{ps}$ and pulse repetition rates of $166\mathrm{kHz}$ . At $1064\mathrm{nm}$ , a linear polarized transversal and longitudinal single-mode beam is emitted. To the best of our knowledge, these are the shortest pulses in the $1\mu \mathrm{J}$ energy range ever obtained with passively Q-switched microchip lasers. The quasi-monolithic setup ensures stable and reliable performance.
