We review recent progress in optical wave turbulence with a specific focus on the fast growing field of fiber lasers. Weak irregular nonlinear interactions between a large number of resonator modes are responsible for practically important characteristics of fiber lasers such as the spectral broadening of radiation. Wave turbulence is a fundamental nonlinear phenomenon which occurs in a variety of nonlinear wave-bearing physical systems. The experimental impediments and the computationally intensive nature of simulation of hydrodynamic or plasma wave turbulence often make it rather challenging to collect a significant number of statistical data. The study of turbulent wave behavior in optical devices offers quite a unique opportunity to collect an enormous amount of data on the statistical properties of wave turbulence using high-speed, high precision optical measurements during a relatively short period of time. We present recent theoretical, numerical and experimental results in optical wave turbulence in fiber lasers ranging from weak to strong turbulences for different signs of fiber dispersion. Furthermore, we report on our studies of spectral wave condensate in fiber lasers that make interdisciplinary links with a number of other research fields.
