A laser pointer or laser pen is a small portable and visible laser designed to highlight something of interest by projecting a small bright spot of colored light onto it. There are several kinds of laser pointers, mainly are green, blue and red laser pointers. The green laser pointer usually with more bright light than the other two, and it is also the most popular laser pointers. So, there are many people who interested in how to make a green laser pointer at home. Here are some guidelines: First you need a room for layout purpose where you can install the pieces of mirror. As you may already know that the Linear cavities are the simplest of all laser cavities, which consist of 2 or 3 mirrors depending on what you want to do. For a simple IR laser, you will need a set of 2 mirrors, a high reflector, or HR for the rear mirror, and an output coupler, OC for the front mirror. And in the room, the more mirrors you install, the green laser light reflection can be produced by your green laser pointer. If you use a high powered green laser pointer above 35mW, you definitely can produce a brighter beam thus making mirror reflection produce brighter beam reflection and make the room brighter. The second step is that you should place the double-sided tape behind the mirrors and install the mirrors on your walls and even your ceiling and floor. The mirror installation does not have any rules in placement, its all about how creative you can be to visualize how your green laser beam reflection will be projected for your green laser light show. Your laser light show will be more flexible if you use an optics set specifically designed to reflect and refract green laser beams from portable green laser pointers. The last step is after installing the mirrors on the walls, you are good to go! Try pointing the portable green laser pointer to one of the mirrors and you will notice another laser beam will be reflected to a different direction. Focus the second beam to another mirror and you will get a third green beam light pointing to another direction. As the beam expands, your room will be brighter and more spectacular. Try using other laser pointers such as red green lasers or blue lasers to produce a different ambiance and projection and the more laser pointers you use bouncing the beams across the room, you can produce a more magnificent laser light show. The images shown in this section is not an actual laser light show done in this presentation but it will give you an idea of the outcome of your project. SO start getting that creative juices flowing and perform your own homemade green laser pointer light show project. I think that covers most everything people get stuck at when planning a DIY DPSS system, it is a complex and expensive project and not something to jump into until you fully understand the cost and requirements.
