Can the computer screen be controlled with a laser pointer?

Although Einstein laid the foundation for the final development of laser technology, he did not play an important role in the development process. Instead, other scientists moved on from where Einstein stopped and tried to prove his theory as they moved forward. One of the scientists was Rudolf Ladenburg, who confirmed Einstein's original theory in the late 1920s. Another scientist is Valentin Fabrikant (Valentin Fabrikant), he adopted Einstein's theory, and on this basis established the theory that emission can be used to stimulate radiation to amplify. Since the 1960s, laser technology has continuously developed and changed the lives of people all over the world. In the 1970s, scientists found a way to use a laser to etch silicon computer chips. In the 1980s, she used her to make laser eye surgery possible. Since then, green laser pointer technology has continued to evolve. It will be interesting to see how the world can push it further in the next 100 years.
