自注入式固体Ce^(3+)∶LuLiF_4激光器中紫外亚纳秒脉冲序列的产生

Ultraviolet Subnanosecond Pulse Train Generation From a Self Injected Solid State Ce 3+ ∶LuLiF 4 Laser

提出一个注入式结构，它可以用在各种脉冲激光器中产生短脉冲序列。在这个结构中，从短腔种子激光器产生单一的亚纳秒脉冲，这个种子脉冲在同一增益介质中被再生放大，直到增益衰减到最小。用一个１０ｎｓ脉冲激光器泵浦固体激光介质Ｃｅ３＋∶ＬｕＬｉＦ４，直接地，被动地产生了紫外亚纳秒脉冲序列。

We propose a passive self injected scheme for the generation of short pulse trains from various pulsed lasers. In this scheme a single subnanosecond pulse is generated from a short cavity seeding laser. The pulse is then returned to the same gain medium and amplified regeneratively until the gain is quenched completely. An ultraviolet subnanosecond pulse train is directly and passively generated from a solid state laser medium (Ce 3+ ∶LuLiF 4) pumped by a standard 10 nsec laser.
