Broadband noncollinear optical parametric amplifier using a single crystal.
Opt Lett 30:13 (2005) 1704-1706
Abstract:
A noncollinear optical parametric amplifier in which blue pump pulse generation as well as parametric amplification takes place in the same nonlinear crystal is presented. Broadband spectra tunable throughout over 100 nm in the visible were generated in a simple setup. The green output pulses were compressed to 65 fs, and efficiency (IR-to-visible) of 1.8% was achieved.Spectral phase interferometry for complete reconstruction of attosecond pulses
Laser Physics 15 (2005) 6
Abstract:
We propose two methods for measuring the complete phase and amplitude of attosecond X-ray pulses produced by high harmonic generation in an atomic gas. These methods are based on spectral shearing interferometry and are achieved by pumping the harmonic source with two spectrally sheared driving pulses. This can be achieved in two configurations: either by having a time delay between the two driving pulses or by separating them spatially in the generation region. We show by numerical simulation that both these techniques are capable of retrieving full field information of the attosecond pulses produced and discuss their experimental implementation.Applied physics.

Complete characterization of attosecond pulses
Journal Of Modern Optics 52 (2005) 2-3
Abstract:
We review the requirements for achieving full phase and amplitude characterization of attosecond X-ray pulses and propose several methods for carrying out such measurements. We show via numerical simulation that these techniques are capable of retrieving full field information of attosecond pulses and compare their performance and ease of implementation.Characterization of the nonclassical nature of conditionally prepared single photons - art. no. 021802
