“…One is used to produce the TLP pulse and the other one contains the "reference pulse" to analyze. Different strategies can be implemented for the production of ultrashort TLP pulses [27]. We have selected a method that relies on the production of two counter-rotating CP and time-delayed chirped pulses.…”

“…The configuration is therefore analog to the sum of two spectrally-shifted CP fields of opposite handedness resulting in the desired TLP pulse. It has been shown [27] that for a Gaussian pulse shape the field vector rotates with a temporal period T rot = 2π/(aT) where a depends on the quadratic spectral phase Φ :…”

“…This effect can for instance be exploited to tune the wavelength of laser fields. In this context, the use of broadband radiations, such as super-continua, to produce the TLP pulse should allow an ultrafast rotation of the field vector inducing controllable giant frequency shift (about √ 2 times the bandwidth of the TLP pulse [27]). Rotational Doppler effect could also be of interest to control the wavelengths of THz fields not otherwise easily accessible.…”

We present a new variant of spectral-shearing interferometry method for characterizing ultrashort laser pulses. This original approach, called Doppler Effect E-field Replication (DEER), exploits the rotational Doppler effect for producing the frequency shear and provides a spectral-shearing in the absence of frequency conversion enabling operation in the ultraviolet spectral range. Evaluation of the DEER-SPIDER setup reveals a phase reconstruction of great reliability. Possible improvements, benefits, and worthwhile prospects of the method are discussed.

Technological advances in femtosecond laser sources call for the development of increasingly refined characterization tools implying to enrich the existing panel of operable nonlinear interactions. Toward that end, we have recently proposed a variant of SPIDER (spectral phase interferometry for direct electric field reconstruction) based on a nonstandard effect for producing the frequency shear, the so-called rotational Doppler effect. The method called DEER-SPIDER, for Doppler effect E-field replication, has the advantage of producing a spectral shearing at/near the fundamental wavelength, thus allowing operation in the ultraviolet spectral range. The present paper provides a deeper study of this approach. The method is tested under two different challenging conditions, and a thorough theoretical analysis is proposed. Possible improvements and an outlook are also discussed.
