摘要
利用质子交换ＭｇＯ∶ＬｉＮｂＯ３平板波导研究了对近红外半导体激光器的切伦科夫倍频特性，实现了对９５６ｎｍ和８０４ｎｍ半导体激光器的直接倍频，得到了４７８ｎｍ的倍频蓝光和４０２ｎｍ的倍频紫光输出。在基频导模功率小于１ｍＷ的低入射功率下，倍频光功率的估算值约在０．１μＷ和０．０１μＷ之间。
Using the proton exchanged MgO∶LiNbO 3 planar optical waveguides,the characters of Cerenkov second harmonic generation of infrared laser diodes were studied,the direct frequency doubling of 956nm and 804nm laser diodes were realized and 478nm blue and 402nm violet light are generated.Under the low fundamental guide wave power of about 1mW,the estimated values of the output powers of the harmonic waves are in the order of 0.1μW to 0.01μW.At last,the experimental results and the problems in our experiment are discussed.
