摘　　要：This paper studies the type-I phase-matched second harmonic generation using 25-fs input laser pulses in a thick BBO crystal. The harmonic signal exhibits a narrow spectrum bandwidth, even though the input pulse has a broad bandwidth. The energy transfer efficiency and modulation of the fundamental spectrum are investigated.This paper studies the type-I phase-matched second harmonic generation using 25-fs input laser pulses in a thick BBO crystal.
