A train of pulses of approx.5 x 10/sup -10/ sec duration and approx.2 x 10/sup -3/ J energy was generated by a periodically Q-switched neodymium glass laser. The width of the emission spectrum was approx.3.0 nm and the contrast of the emitted radiation exceeded 10/sup 3/. Pulse generation started after 10--20 passes through the resonator. The pulses could be synchronized with external apparatus to within approx.10/sup -9/ sec. Stable generation of pulse trains was observed when the pumping rate exceeded considerably the threshold value. A laser of this kind could be used as a source of short pulses which could then be amplified effectively in high-power neodymium-glass systems.
