A laser was constructed in which the active medium was a crystal of calcium lithium niobium gallium garnet activated with Nd3+ ions. An acoustooptic modulator made of an LiNb03 crystal and a passive LiF switch with F2 colour centres were used in this laser. The combination of active mode locking and Q switching made it possible to generate laser pulses of 10-15 ps duration at the wavelength λ = 1061.2 nm with a peak power of about 15 MW. © 1994 Kvantovaya Elektronika and Turpion Ltd.
