What is the first laser pointer in your life?

In the past few decades, high powered laser pointer technology has made great strides. So the interesting question is what is the first laser pointer you have? For many of us, a simple low-power red laser keychain is the norm. They are often purchased from flea markets and street vendors. They feature hats that can be added to lasers for visual designs such as female silhouettes, grid effects, and dog shapes. Its function is that it is a laser beam and a point that travels a short distance and can actually be seen even at night. We can’t see the beam unless in the fog or smoke, but for most of us, this is still the beginning of the laser world, and it’s very interesting.
