[12] 後來，Fejer等人對雷射加熱平台成長技術做出了一項突破性的改良。 [13] 他們結合了一種稱為"reflaxicon"的特殊光學元件，"reflaxicon"的構造由兩同軸錐面反射鏡所組成，一內一外將入射雷射光散成無數道往不同方向的反射光。這些反射光經其它面鏡反射後，最後

Among all advances, the introduction of the reflaxicon by Fejer et al. [24,25] may be highlighted. It enabled a circular, crown-shaped laser beam focus and, therefore, uniform radial heating. This term describes a setup of a two-stage pair of reflective linear axicon surfaces [21], which was invented by Martin in 1948 [26] and later improved by

A new two-stage axiconic reflector called a reflaxicon is discussed. This device consists essentially of a primary conical mirror and a larger secondary conical mirror located coaxially with respect to the primary mirror. The secondary mirror is truncated at such a location that the inner diameter of the secondary mirror (the diameter of the hole) exceeds the base diameter of the primary mirror.

Reflaxicon. Special features and Bessel beam shaping Applications Other Reflaxicons Research References. An axicon is a specialized type of lens that has a conical surface. An axicon transforms a laser beam into a ring shaped distribution. [1] They can be convex or concave and be made of any optical material. The combination with other axicons
