“…The latter is limited because material dispersion imposes that, for a given wave interaction configuration, the exact phase-matching condition can be strictly satisfied only for a single set of wavelengths of the three waves. Presently the most common way to achieve the combination of broadband and high amplification is to use chirped quasi-phase-matching [5][6][7][8][9][10]. Even though chirped quasi-phasematching approaches have the advantage of being broadband, they require high pump input intensity and/or very long nonlinear crystals.…”

We propose a novel optical parametric amplification scheme which combines quasi-phase-matching with a composite pulse approach that involves crystal segments of specific lengths. The presented scheme highly increases the robustness of the frequency conversion against variations of the nonlinear coupling and of the pump, idler or signal wavelengths and has therefore the potential to enhance high amplification and broadband operation. Simulations examples applied to LiNbO3 are given. PACS numbers:

“…Another approach is to choose a generation wavelength that allows compensation of the entire bandwidth by a single phase-matching condition, which is possible when the central bi-photon frequency is matched to the zero dispersion of the nonlinear medium. Ultra-broad phase matching of the nonlinear down-conversion interaction, has been widely discussed [4][5][6][7][8][9][10]. In [6,9,10] for example, the broad bandwidth is achieved by chirping the quasi-phase matching period along the crystal.…”

Octave-spanning spectral phase control for single-cycle bi-photons

et al. 2015

The quantum correlation of octave-spanning time-energy entangled bi-photons can be as short as a single optical cycle. Many experiments designed to explore and exploit this correlation require a uniform spectral phase (transform-limited) with very low loss. So far, transform-limited single-cycle bi-photons have not been demonstrated, primarily due to the lack of precise, broadband control of their spectral phase. Here, we demonstrate the correction of the spectral-phase of near-octave spanning bi-photons to 20 φ π < over an octave in frequency 1330 ≈ -2600 nm). Using a prism-pair with an effectively negative separation for shaping the bi-photons' spectral phase, we obtain a tuned, very low-loss compensation of both the second and fourth dispersion orders. An essential requisite for precise tuning over such a broad bandwidth is a measure of the spectral phase that provides feedback for the tuning even when the overall dispersion is far from compensated. This is achieved by a nonclassical bi-photon interference, which enables direct verification of the corrected bi-photon spectral phase.

“…Since the relative change in period is small, fabricating a grating whose period smoothly varies between these periods is possible with comparable lithographic poling procedures as used for PPLN devices. This property also means that APPLN devices are well suited for mid-IR seed generation via DFG [11,19].…”

Abstract:We demonstrate a new regime for mid-infrared optical parametric chirped pulse amplification (OPCPA) based on achromatic quasi-phase-matching. Our midinfrared OPCPA system is based on collinear aperiodically poled lithium niobate (APPLN) pre-amplifiers and a non-collinear PPLN power amplifier. The idler output has a bandwidth of 800 nm centered at 3.4 µm. After compression, we obtain a pulse duration of 44.2 fs and a pulse energy of 21.8 µJ at a repetition rate of 50 kHz. We explain the wide applicability of the non-collinear QPM amplification scheme we used, including how it can enable octave-spanning OPCPA in a single device when combined with an aperiodic QPM grating.
