摘要：
The output characteristics of a two-colour Nd3+:YAG laser with a dispersive cavity, emitting at 1.32 and 1.06 mum, are considered. The enlargement of the region of stable two-colour lasing, due to the reduced competition in the case of spatially separated channels, is demonstrated. The influence of the size of the pumped region on the laser efficiency and the competition between the lasing channels is studied. It is shown that, in the case of a single pump source, the weakening of the competition between the waves is accompanied by a reduction in the laser efficiency. A novel construction of the two-channel laser with two pump sources is proposed, which offers increased stability without the reduction in the efficiency.
