摘要:
系统的介绍了我国深紫外非线性光学晶体的发展,主要以KBe_2BO_3F_2(KBBF)以及Sr_2Be_2B_2O_7(SBBO)族晶体为代表。通过晶体生长、确定结构以及各种光学性能的测定,发现KBBF晶体是目前唯一能采用直接倍频方法实现深紫外谐波光输出的非线性光学晶体。SBBO族晶体由于存在畴结构,目前还不能用于深紫外相干光输出。讨论了KBBF晶体的基本光学性质以及产生深紫外相干光源的能力和效率。介绍了这些深紫外相干光源的应用,并着重介绍了这些光源在先进能谱仪方面的应用及取得的重要成果。

This review systemically introduces the development of deep ultraviolet (UV)nonlinear optical crystals,especially for KBe_2BO_3F_2 (KBBF)crystal and Sr_2Be_2B_2O_7 (SBBO)family.Based on the crystal growth,space structure determination as well as the measurements of optical properties,we find that crystals in the SBBO family have domain structures that limit their application to UV harmonic generation.KBBF is now the only crystal to produce deep-UV coherent light just using second harmonic generation.Then the optical properties and deep UV harmonic generation of KBBF crystal is discussed in detail.Finally,the applications of the deep UV laser are introduced,as in the advanced photoemission spectrometer in particular.
