We report on an efficient high-power, widely tunable femtosecondopticalparametricoscillator inBiB3O6, synchronously pumped by a frequency-doubled mode-locked Yb: KGW laser at 515 nm. Using collinear type I (o → e e) phase matching, a resonant wavelength range of 688– 1057 nm at a 151-MHz repetition rate is demonstrated, with a tunable idler range of 1150–1900 nm. The output power at 705 nm is 1...
Techniques to measure and manipulate the carrier-envelope phase within femtosecond optical parametric oscillators (OPOs) allow their outputs to be stabilized in a way that produces a frequency comb structure, potentially tunable throughout the transparency band of the gain material. In this review we describe the fundamental principles of phase control, on which the development of singlyand dou...
A recent experimental demonstration of a parametric magnetization oscillation excited by applying microwave voltage to ferromagnetic metal will be applicable not only new switching method but also bio-inspired computing. It should be, however, noted that phase the is uniquely locked, related fact frequency twice value oscillation. There are two possible phases in state, and which realized depen...
The temperature tuning of BaGa4Se7 (BGSe) was demonstrated for the first time, to best our knowledge. When BGSe (56.3°,0°) raised from 30°C 140°C, idler light under type I 3637 nm 3989 nm, tunable range reached 352 and ??2/?T 3.20 nm/°C. We calculated phase matching curve when ? T took different values. relationship between ? obtained by fixing at 0°. maximum its corresponding (?, ?) were repor...
