Coherent optical emission of free induction decay (FID) excited by the multiple-photon resonance has been recently observed in nitrogen ions produced by intense femtosecond laser *** we report that orbit angular momentum (OAM) of the pump laser pulses can be transferred to the much longer pulsed free induction decay emission with the OAM *** was found that when the pump laser frequency approaches the fraction of the 391.4 nm emission (ν_(0)/5),an FID emission is emitted whereas its topological charge was identified to be 5 times of the pump *** to the reduced laser intensity with a vortex pump compared to the conventional Gaussian beam,the resonant pump laser wavelength presents a redshift,and the FID signal is significantly weaker.

A pair of photons called signal and idler photons, respectively, are produced through the nonlinear process of type I spontaneous parametric down conversion in BBO crystal pumped by the second harmonic wave of a Ti∶sapphire femtosecond laser pulse. The two order interference phenomenon of the signal photon in Michelson interferometer is observed and give an analysis in detail.

The presence of pulse front tilt(PFT),caused by angular dispersion(AD)in femtosecond laser pulses,could degrade the performance of the laser system and/or impact the experimental *** present a single-shot diagnostic capable of measuring the AD in the x–y plane by adopting an intensity *** can be applied to stretched pulses,making it ideal for diagnosing the AD along the amplification chain of a high-power laser system,and to ultrashort pulses exiting from an optical *** this way,it can help in properly characterizing a laser pulse before it is delivered to the target *** this Letter,we present experimental evidence of AD retrieval for different compression configurations,supported by theoretical analysis.
