We report a novel integrated Q-switched laser constructed from a bulk domain-inverted single Nd:LiTaO(3) crystal that combines the laser gain and the electro-optic effect. The Q of the cavity is controlled electro-optically by exploitation of the deflection that occurs at the boundary of two oppositely directed domains under the application of an electric field. The integrated Q-switching element, with dimensions of 4.1 mm x 4.6 mm x 1 mm, generates 22-ns pulses at 1.08 microm with a peak power of 64 W and an operating voltage of ~600 V. The output is seen to be completely free from prelasing or afterpulsing.
我们报道了一种新型集成调Q激光器，它由一块体畴反转的单Nd:LiTaO(3)晶体构成，该晶体兼具激光增益和电光效应。通过利用在施加电场时两个相反方向畴的边界处发生的偏转，以电光方式控制腔的Q值。这种尺寸为4.1毫米×4.6毫米×1毫米的集成调Q元件，在1.08微米波长处产生22纳秒的脉冲，峰值功率为64瓦，工作电压约为600伏。输出完全没有预激射或后脉冲现象。
