DOIAbstract
International audienceUltrashort self-guided laser pulses are employed to generate high-order harmonics in noble gases. Interference fringes between fundamental and harmonic waves over several cm reveal a long range longitudinal coherence of the generated harmonics. Quasiphase matching is demonstrated for the third harmonic wave
