Abstract:
An investigation was made of the energy, time, and spectral characteristics of resonator picosecond optical parametric oscillators made of LiNbO3, CsH2AsO4, and Ba2NaNb5O15 crystals. The maximum conversion efficiencies in these crystals were 5.3, 7.2, and 12.5%, respectively. The output wavelength was tunable within the range 0.65–3 µ.
