Abstract

The invention relates to a microlaser cavity (10) having: PA1 a solid active medium (2) emitting at least in a wavelength range between 1.5 and 1.6 .mu.m, and PA1 a saturable absorber (4) of formula CaF.sub.2 :Co.sup.2+ or MgF.sub.2 :Co.sup.2+ or SrF.sub.2 :Co.sup.2+ or BaF.sub.2 :Co.sup.2+ or La.sub.0.9 Mg.sub.0.5-x Co.sub.x Al.sub.11.433 O.sub.19 or YAlO.sub.3 :Co.sup.2+ (or YAl.sub.5-2x Co.sub.x Si.sub.x O.sub.3) or Y.sub.3 Al.sub.5-x-y Ga.sub.x Sc.sub.y O.sub.12 :Co.sup.2+ (or .sub.-3 Al.sub.5-x-y2z Ga.sub.x Sc.sub.y Co.sub.z Si.sub.z O.sub.12) or Y.sub.3-x Lu.sub.x Al.sub.5 O.sub.12 Co.sup.2+ (or Y.sub.3-x Lu.sub.x Al.sub.5-2y Co.sub.y Si.sub.y O.sub.3) or Sr.sub.1-x Mg.sub.x La.sub.y Al.sub.12-y O.sub.12 :Co.sup.2+ (or Sr.sub.1-x Mg.sub.x-y Co.sub.y La.sub.z Al.sub.12-z O.sub.12, with o<y<x).
