The fifth harmonic generation by mixing Nd:YAG laser fundamental and its fouth harmonic radiation using BBO crystal at room temperature is reported. The energy conversion efficiencies of fourth hamonic to fifth harmonic as high as 48% have been achieved. A numerical method was used to analyse the process of mixing 1064 nm and 266 nm and its result is in agreement with the experimental result.
