Yes. I saw a demonstration where a professor used a custom-built system consisting of: a speaker with a solar panel wired into the input line, and a laser pointer wired into the output line of an iPod. When the iPod played, it caused the laser pointer to activate, sending the beam (and energy) to the solar panel, which powered the speakers. He sent some music across the room with it. It was a great little project.

White laser pointers have several advantages over other colored laser pointers. One key feature is their ability to produce a brighter and more visible beam, making them ideal for presentations and pointing out objects from a distance. Additionally, white laser pointers are less likely to cause eye strain compared to colored lasers, as the white light is easier on the eyes. Another benefit is that white laser pointers can be used on a variety of surfaces, including screens and whiteboards, without losing visibility. In contrast, colored laser pointers may not be as visible on certain surfaces and can be harder to see in well-lit environments.
