Ce travail de thèse se développe autour de trois expériences. La première concerne la mesure du rapport h/m entre la constante de Planck et la masse d'un atome de rubidium. Dans le cadre de l'étude détaillée des effets systématiques, tels que la phase de Gouy ou l'effet Zeeman quadratique, nous avons développé une nouvelle source laser compacte et puissante (12W@780nm) permettant de réduire l'effet de la phase de Gouy d'un facteur 4. La deuxième expérience a porté sur la démonstration d'un nouveau schéma de gravimètre compact, s'appuyant sur les oscillations de Bloch pour faire léviter les atomes. Une mesure de l'accélération locale de la pesanteur a été réalisée avec une sensibilité préliminaire très prometteuse de 4.7E-7 g en 1s. La trois...
