Abstract

A New Expander Mechanism of an Infrared Laser Based on Different Nanometre Quantum Dot Particles

The traditional beam expander mechanism is derived from the Galilean and Kepler telescopes and the glass prism, which have been used for hundreds of years. Our experiments reveal that two different ITO quantum dots and NaYF4:Yb, Er nanometre particles mixed uniformly can be used to realize a Laser beam expander. The expander can be detected only by a CCD electronic camera. The expander of the infrared laser does not depend on a prism; it is a novel quantum mechanism. The mixed nanometre powder 0.2-1 mm-thickness wafer can expand the laser light spot by 2-4 times. Although the expanded laser light energy strength clearly decreases, it can still be detected well by the CCD camera. The new mechanism supplies a new possibility for improving infrared laser range radar finders, positioning, 3D processing and laser disc information storage.
