Microlaser cavity, a solid state pulsed microlaser with active Q-switching by a micromodulator and method forming same

Abstract

The invention relates to a microlaser cavity, with active Q switching, characterized in that it comprises: an active laser medium (20), an input mirror (22) and an output mirror (24, 87) defining the cavity, a micromodulator with frustrated total internal reflection, comprising two microprisms (32, 34) made of a certain material of index n.sub.1 each having at least one planar face (36, 38), the two planar faces being approximately parallel to each other and inclined on the microlaser cavity axis, thereby defining a plate (30) of a certain material of index n.sub.2 less than n.sub.1. means (44, 46, 48, 50, 52, 54) for varying the thickness of the plate.
