In previous studies, his research team proved that at microwave frequencies, this mechanism can effectively capture and store light, enhancing the interaction between light and matter. Now, they use continuous bound states for the demonstration of new laser pointer. The team’s research work was published in the January 12th issue of Nature.
The continuous bound state laser in this work is made of a thin indium, gallium, arsenic, and phosphorous semiconductor film. The membrane structure is a nano-array of cylinders suspended in the air. The cylinders are interconnected by a network of supporting bridges, which provides the mechanical stability of the equipment. Using a high-frequency laser beam to drive the membrane, the researchers induced a continuous bound state system to emit its own lower frequency laser beam (at the telecommunication frequency). Now, this is a proof of concept demonstration, we can indeed realize the interaction between laser and continuous bound state.
He said: “It’s worth noting that we can get an array of green laser pointer generation on the surface, whose size is as small as 8×8 particles. In comparison, it is widely used in data communication and high-precision sensing surface lasers. (Vertical Cavity Surface Emitting Laser), a larger size (100 times) is required, so more energy is needed to realize the array laser. One day it will be replaced by what we call continuous bound state surface emitting laser, which will achieve smaller The equipment consumes less power. The research team has applied for a patent for this new light source.
The array can also be scaled up to create high-power lasers for industrial and defense applications, he pointed out. A basic challenge in high-power laser systems is heating, and the predicted efficiency of our continuous bound state laser technology. A new era is becoming possible. The next step of the research team’s research plan is to make an electrodynamically driven continuous bond. State laser instead of being powered by another laser. An electrically pumped laser is easy to carry outside the laboratory and can be powered by a traditional battery.
