千瓦级功率脉冲Nd:YAG激光器
摘要：
本发明公开了一种千瓦级功率脉冲Nd:YAG激光器。它的谐振腔反射镜间置有由掺钕钇铝石榴石晶体、陶瓷漫反射聚光腔和激励源构成的Nd：YAG泵浦组件；其中，谐振腔反射镜为表面镀1064nm全反膜的第一全反镜(M1)、第二全反镜(M2)、第三全反镜(M3)和45゜角全反镜(M4)，以及一面镀1064nm增透膜、另一面镀1064nm的50％透过膜的45゜角半反镜(M5)，Nd：YAG泵浦组件中的第一Nd：YAG泵浦组件(1)两端置有第一全反镜(M1)、45゜角全反镜(M4)、45゜角半反镜(M5)和第三全反镜(M3)，第二Nd：YAG泵浦组件(2)两端置有第二全反镜(M2)、45゜角半反镜(M5)、第三全反镜(M3)和45゜角全反镜(M4)。它输出高达1000W，极易于广泛地商业化应用于焊接和切割及国防等领域。
摘要（英）：

The invention discloses a kilowatt power pulsed Nd:YAG laser device. The kilowatt power pulsed Nd:YAG laser device comprises resonant cavity reflectors, wherein Nd:YAG pump assemblies each composed ofa neodymium-doped yttrium aluminum garnet crystal, a ceramic diffuse reflection condensing cavity and an excitation source are arranged among the resonant cavity reflectors; the resonant cavity reflectors are respectively a first total reflection mirror (M1), a second total reflection mirror (M2), a third total reflection mirror (M3) and a 45-degree angle total reflection mirror (M4) of which thesurfaces are plated with 1064 nm total-reflection films, and a 45-degree angle semi reflection mirror (M5) with one surface plated with a 1064 nm antireflection film and the other surface plated witha 1064 nm 50% transmissive film; both ends of the first Nd:YAG pump assembly among the Nd:YAG pump assemblies are provided with the first total reflection mirror (M1), the 45-degree angle total reflection mirror (M4), the 45-degree angle semi reflection mirror (M5) and the third total reflection mirror (M3); and both ends of the second Nd:YAG pump assembly are provided with the second total reflection mirror (M2), the 45-degree angle semi reflection mirror (M5), the third total reflection mirror (M3) and the 45-degree angle total reflection mirror (M4). The output of the kilowatt power pulsedNd:YAG laser device is up to 1000 W, and the kilowatt power pulsed Nd:YAG laser device is easily, widely and commercially applied to the fields of welding, cutting, national defense and the like.
