Crystal Growth of Cerium Doped KTP and Its Efficient Generation of Coherent Blue Light
【摘要】 采用熔盐法生长了光学质量的 Ce:KTP晶体。透过曲线表明 ,Ce:KTP在紫外截止波段附近的吸收比普通 KTP低约 10 %。采用 KTP晶体的倍频以及 Ce:KTP和频的组合 ,利用 Nd:YAG激光器的 1.32μm单一输出线束作抽运 ,实现了 0 .4 4μm相干蓝光的有效发生 ,其总效率约为2 .5%。
【Abstract】 Cerium doped potassium titanyl phosphate crystals with optical quality were grown using a flux method. Optical transmission spectrum shows that the absorption of Ce∶KTP in the blue domain was noticeable reduced. Using a coupling of SHG of a KTP crystal and SFG of Ce∶KTP, the efficient coherent blue light was generated by a Nd∶YAG single 1.32 μm beam as a pump and the overall efficiency is about 2.5%.
