Abstract:
1. A laser device comprising: a laser chamber having a volume formed therein; a gain medium within the volume and comprising a solid-state element containing active laser ion within the volume, the solid-state element rigidly held in a fixed position within the volume; a fluid flowing about the solid-state element; a semiconductor laser diode for providing optical pump radiation into the volume of the laser chamber; and a laser emission from the solid state element passes through the gain medium and the fluid; wherein a dimension L of the solid state element is defined by: where ΔT is a maximum temperature difference between a center and a surface of the solid state element, k s is a thermal conductivity of the solid state element, c is a geometric constant wherein c is a value between 4 and 8, and q′″ is a heat generated per unit volume within the solid state element resulting from diode-pumping.
