Picosecond Resolution in Field Cross-Correlation Experiments with Nanosecond Sources

Abstract

Field cross correlation is used to attain picosecond or sub-picosecond resolution in the time domain analysis of coherent optical emission triggered by long broad bandwidth light pulses. Optical data recording and retrieval is demonstrated in gaseous and in solid samples.

Picosecond resolution in amplitude cross-correlation experiments with nanosecond sources

A. Bouchene, Anne Débarre, J. Keller +2 more

Although ultrashort laser pulses are usually needed for the optical exploration of ultrafast relaxation processes, it is known that the same time resolution can be attained with long duration pulses, provided their coherence time τc is shorter than the investigated process characteristic time. A time delayed four-wave mixing configuration is then used.

Fast Sampling of Atomic Velocities by Incoherent Light Stimulated Photon Echoes

M. Defour, J. Keller, J.-L. Le Gouët

It has been recently pointed out that incoherent light can be used to generate coherent optical transients and that there are decided advantages in using such broad-band non-laser source to achieve very high time resolution {1,2}. When a light pulse and its time-delayed replica interact with a sample to produce the non-linear optical response, the ultimate time resolution should identify with the correlation time τC of the light field rather than with the pulse duration τL. The situation where τC ≪ τL is easily obtained with broad-band incoherent light sources. Time resolution in the femtosecond range is then attainable using nanosecond light pulses. This has been recently demonstrated through the observation of the relaxation of photon echoes in Nd3+-doped silicate glass {1,2}. In these cases, attention is focused on the measurement of fast homogeneous decay rates and the inhomogeneous broadening ΩD is assumed to be much larger than the spectral width of the excitation light.

Field cross-correlation retrieval of optically stored data

Anne Débarre, J. Keller, J.-L. Le Gouët +1 more

A new method is studied for reading data that have been optically stored within the inhomogeneous spectral width of a material. The memory element is illuminated by a broad-bandwidth laser pulse. The signal that results from this excitation is analyzed by cross correlation with the field of a reference pulse, which is nothing but a delayed replica of the read pulse. Theoretical and experimental aspects of this process are discussed.

Picosecond Dephasing Time Measurement by CSRS Using Temporally Incoherent Nanosecond Laser with Short Correlation Time

Takayoshi Kobayashi, Toshiaki Hattori, Akira Terasaki

Until now all reported studies of transient spectroscopy with incoherent light, including photon echo and pump-probe spectroscopy, were concerned with two-level systems where quasi-monochromatic light of only one frequency couples the two levels.[1-4] However, there exist various coherent transient phenomena where light of two or more frequencies are concerned, and time resolution of the transient spectroscopies using these phenomena are also expected to be limited not by the duration of used light pulses but by the correlation time of the radiation fields.[5]

Measuring the dynamics of second-order photon correlation functions inside a pulse with picosecond time resolution

Marc Aßmann, Franziska Veit, Jean-Sebastian Tempel +5 more

We present a detailed discussion of a recently demonstrated experimental technique capable of measuring the correlation function of a pulsed light source with picosecond time resolution. The measurement involves a streak camera in single photon counting mode, which is modified such that a signal at a fixed repetition rate, and well defined energy, can be monitored after each pulsed laser excitation. The technique provides further insight into the quantum optical properties of pulsed light emission from semiconductor nanostructures, and the dynamics inside a pulse, on the sub-nanosecond time scale.
