High-power, continuous-wave, second-harmonic generation at 532 nm in periodically poled KTiOPO(4).
We report efficient generation of high-power, cw, single-frequency radiation in the green in a simple, compact configuration based on single-pass, second-harmonic generation of a cw ytterbium fiber laser at 1064 nm in periodically poled KTiOPO(4). Using a crystal containing a 17 mm single grating with period of 9.01 microm, we generate 6.2 W of cw radiation at 532 nm for a fundamental power of ...
متن کاملHighly efficient second-harmonic generation in buried waveguides formed by annealed and reverse proton exchange in periodically poled lithium niobate.
Efficient three-wave mixing devices have numerous applications, including wavelength conversion, dispersion compensation, and all-optical switching. Second-harmonic generation (SHG) is a useful diagnostic for near-degenerate operation of these devices. With buried waveguides formed in periodically poled lithium niobate by annealed and reverse proton exchange, we demonstrate what is believed to ...
متن کاملFemtosecond second-harmonic generation in periodically poled lithium niobate waveguides with simultaneous strong pump depletion and group-velocity walk-off
We report studies of second-harmonic generation (SHG) of femtosecond pulses in long periodically poled lithium niobate waveguides under large conversion conditions. Strong saturation of the SHG efficiency was observed, accompanied by spectral and temporal distortion of the pump pulse. Our simulation studies suggest that the pulse distortions may be caused by the interaction of the phase-matched...
متن کاملNonlinear Integrated Optics with Periodically Poled Waveguides in LiNbO3
The advent of the electric field poling method to fabricate periodically poled, ferroelectric, nonlinear optical materials resulted in a renaissance of nonlinear optics. Since then quasi-phase matching has been used for efficient wavelength conversion in devices like frequency doublers, difference frequency generators (DFG) and optical parametric oscillators (OPO). Periodically poled Lithium Ni...
متن کاملQuasi-phase-matched difference-frequency generation in periodically poled Ti:LiNbO(3) channel waveguides.
Mid-infrared radiation near 2.8 mum was generated by difference-frequency generation in an 80-mm-long periodically poled Ti:LiNbO(3) channel waveguide by pump radiation near 1.55 mum (tunable external-cavity laser) and a signal radiation of 3.391 mum (HeNe laser). We obtained a normalized conversion efficiency of 105% W(-1) , which is to our knowledge the highest value ever reported.
