This article reviews recent theoretical and experimental investigations in the development of femtosecond lasers based on optical parametric oscillators. Phenomena responsible for producing tunable high-power femtosecond pulses in media with quadratic susceptibility (parametric chirp, chirp reversal in real time, parametric self-compression of pulses with strong energy exchange) are discussed.
