چکیده
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 1.09W for 3.6Wpumppower exceeding 30% conversion efficiency.

Tunable, high-power, solid-state sources for the blue and ultraviolet
We describe new sources of tunable, high-power radiation in the blue and ultraviolet. Continuous-wave (cw), singlefrequency blue radiation tunable across 425-489 nm and femtosecond ultraviolet (UV) radiation tunable across 250-355 nm is generated by intracavity frequency-doubling of resonant signal radiation in cw and ultrafast optical parametric oscillators (OPOs) in singly-resonant oscillator...
متن کاملBiB3O6 femtosecond optical parametric oscillator.
We report a femtosecond optical parametric oscillator (OPO) based on the nonlinear material BiB3O6. The OPO is synchronously pumped in the blue by the second harmonic of a Kerr-lens-mode-locked Ti:sapphire laser. It can provide wide and continuous tuning across the entire green-yellow-orange-red spectral range with a single crystal and a single set of mirrors. Using a 500 microm BiB3O6 crystal ...
متن کاملHigh average power, widely tunable femtosecond laser source from red to mid-infrared based on an Yb-fiber-laser-pumped optical parametric oscillator.
We report on the highly efficient generation of widely tunable femtosecond pulses based on intracavity second harmonic generation (SHG) and sum frequency generation (SFG) in a MgO-doped periodically poled LiNbO(3) optical parametric oscillator (OPO), which is pumped by a Yb-doped large-mode-area photonics crystal fiber femtosecond laser. Red and near infrared from intracavity SHG and SFG and in...
متن کاملBroadly tunable mid-infrared femtosecond optical parametric oscillator using all-solid-state-pumped periodically poled lithium niobate.
We describe a high-repetition-rate femtosecond optical parametric oscillator (OPO) that was broadly tunable in the mid infrared. The all-solid-state-pumped OPO was based on quasi-phase matching in periodically poled lithium niobate. The idler was tunable from approximately 1.7 mum to beyond 5.4 mum, with maximum average power levels greater than 200 mW and more than 20 mW of average power at 5....
متن کاملObservations of complex frequency comb structure in a harmonically-pumped femtosecond optical parametric oscillator
Various schemes allow femtosecond optical parametric oscillators to produce pulses at harmonics of their pump laser repetition frequency, each apparently offering the possibility of generating widely-spaced, tunable frequency combs. Using a 100-MHz Ti:sapphire pump laser, we have compared two alternative optical parametric oscillator architectures, both leading to 300-MHz pulses but one configu...
