Velocity-selective Saturated Spectroscopy with a Train of Ultra-short Pulses and a Diode Laser

Abstract

A mode-locked 1 GHz femtosecond laser together with a diode laser is used to perform coherent spectroscopy of the D2 rubidium line. The results are well described using the Bloch equations in the frequency domain picture.

Solitary resonance observed in the saturated absorption spectrum of the 87 Rb D 2 line

Normand Cyr, M. Têtu

In recent years, much work has been done in experimental studies to frequency lock laser diodes to atomic or molecular resonances.1 By such techniques it is possible to improve greatly the laser frequency stability and to define precisely its nominal value. For laser sources operating in the 0.8-μm range, rubidium is the preferred specie and each isotope offers two resonance lines, one at 780 nm (D2 line) and one at 795 nm (D1 line). Both linear and saturated absorption have been used, and laser frequency charcteristics are published.2,3

Using a diode laser and a 1 GHz femtosecond pulse train, we investigate the Autler-Townes splitting and the influence of an electromagnetic induced transparency window in the coherent blue light generated in rubidium vapor.

Two-photon transitions driven by a combination of diode and femtosecond lasers

Marco Polo Moreno de Souza, Giovana Trevisan Nogueira, D. Felinto +1 more

We report on the combined action of a cw diode laser and a train of ultrashort pulses when each of them drives one step of the 5S-5P-5D two-photon transition in rubidium vapor. The fluorescence from the 6P(3/2) state is detected for a fixed repetition rate of the femtosecond laser while the cw-laser frequency is scanned over the rubidium D(2) lines. This scheme allows for a velocity selective spectroscopy in a large spectral range including the 5D(3/2) and 5D(5/2) states. The results are well described in a simplified frequency domain picture, considering the interaction of each velocity group with the cw laser and a single mode of the frequency comb.

Coherent interactions of a mode-locked pulse train with a two-photon Lambda structure

Ladan Arissian, Jean‐Claude Diels

Coherent four photon interaction between a mode locked pulse train and rubidium is investigated. The result of that interaction can be used as a calibration for the frequency comb of a stabilized mode-locked laser.
