An optical element exhibits either an up conversion light emitting characteristic or a light amplifying characteristic when irradiated with exciting light. The optical element includes a bulk glass having titanium oxide as a main component and the glass contains a rare earth element. As the rare earth element, for instance, at least an element of Er or Yb, and a combination of Yb and Tm are suitably used.
Un élément optique présente soit une caractéristique d'émission de lumière à conversion augmentée soit une caractéristique d'amplification de lumière lorsqu'il est irradié par une lumière d'excitation. L'élément optique comprend un verre en vrac ayant un oxyde de titane comme composant principal et le verre contient un élément des terres rares. Comme élément des terres rares, par exemple, au moins un élément de Er ou Yb et une combinaison de Yb et Tm utilisés de façon appropriée.
