We describe the single-beam optical trapping of microscopic KTiOPO4 crystals, using Nd:YAG and Ti:Al2O3 lasers. The high power density of the laser beam at the crystals to be trapped induces the second-harmonic and sum-frequency generation. By changing the wavelength of the Ti: Al2O3 laser, we detect the sum-frequency generation with the fixed wavelength of Nd:YAG laser between 430 and 486 nm for the particle during the trapping.
