Many scientific and technological applications require the generation of broadly tunable femtosecond light pulses. Optical parametric amplifiers (OPAs) exploit second-order nonlinear interactions to convert a high-power fixed wavelength pulse (the pump) into a tunable pulse (the signal). This paper reviews the principles of OPAs and highlights their capability to generate few-optical-cycle pulses with high energy and carrier-envelope-phase stability.
