Continuous tunable mid IR generation is analyzed by difference frequency generation (DFG) in an optical parametric oscillator (OPO). The periodically poled KTiOPO 4 (PPKTP) crystals are used for DFG of position tuning, temperature tuning and noncollinear angle tuning. Using position tuning and tempe

We present simultaneous phase matching of optical parametric oscillator (OPO) and difference frequency generation (DFG), using a noncollinear interaction in periodically poled crystal with single grating. Selecting proper grating period K and titled angle n between the grating vector G and the optic
