This course provides detailed knowledge on the operation and design of nonlinear frequency conversion devices. The emphasis is on frequency conversion in (2) nonlinear crystals, such as frequency doubling, sum and difference frequency generation and parametric oscillation. In addition, Raman amplifiers and lasers (including bulk and fiber-based devices) are treated, and briefly also Brillouin fiber lasers. The course gives an overview of nonlinear crystal materials and addresses the details of phase matching, showing how a certain phase-matching configuration may be chosen based on given device requirements. For various cases, it is shown how to estimate the achievable conversion efficiency. The conversion of short and ultrashort optical pulses is also discussed. Some case studies demonstrate the influence of various practical issues.
