: Include a screenshot of the tuning curve with markers for your operating point. Also show the gain bandwidth (typically ~5-10 nm for KTP). Example 3: Sum-Frequency Generation (SFG) in LiNbO₃ Goal : Mix 1064 nm and 1550 nm to produce 630 nm (useful for biomedical imaging).

: KTP (KTiOPO₄) – high nonlinearity, low walk-off. crystal nonlinear optics with snlo examples pdf

Introduction Nonlinear optics (NLO) is the backbone of modern photonics, enabling technologies such as frequency doubling, optical parametric oscillation (OPO), and terahertz generation. At the heart of these processes are nonlinear optical crystals—materials like BBO, KTP, and LiNbO₃—whose phase-matching properties dictate device performance. However, designing a nonlinear optical experiment or device requires more than just selecting a crystal; it demands precise calculation of phase-matching angles, walk-off, effective nonlinear coefficients, and conversion efficiencies. This is where SNLO (Software for Nonlinear Optics) becomes indispensable. : Include a screenshot of the tuning curve
