In this experiment, we have generated tunable UV radiation (392.5-411.5 nm) using Type- I Sum Frequency Generation (SFG) of dye laser having tuning range 620-670 nm (DCM dye) and 1064 nm from Nd:YAG laser in BBO crystal. Calculated values of phase matching angles with experimental results are also verified. In addition, the theoretically calculated values of angular and spectral bandwidth of SFG in BBO crystal are experimentally verified.
