How to install the laser pointer?
One hunch is that a green laser pointer should just be a good thing. It allows presenters to highlight specific features on their slides, such as points on data graphs, data values ​​in tables (yes, you won't be able to resist the temptation to include tables in PowerPoint slides) or bullets on individual slides A specific bullet in a list. But I would say that any use of a high power laser pointer will only reinforce where PowerPoint makes the speaker go wrong.
This is a serious point. In a presentation, the focus should be on the speaker, and PowerPoint lets many speakers slide into the background, making the sides the center. The speaker just adds scripted comments, not a conversation with the audience. Slides sound like a help, but they're all too easily allowed to take over. And the laser pointer just exaggerates that. Speakers can stay in the shadows, directing the audience more towards the slides.

The level of laser pointer power that is allowed to be used
Only very low power Class II and Class IIIa 300mw laser pointers are allowed. When the selected output power of the laser pointer exceeds 5mW, it is assumed that the laser beam directly into the eye may cause serious eye damage, such as permanent blindness. In many countries, the procurement of laser pointers is very restrictive, and only very low-power Class II and Class IIIa laser pointers are allowed. The market is flooded with a plethora of laser pointers, but most people still choose green laser devices as night lighting for all kinds of presentations. For example, the 532nm green laser pointer is widely used in demonstrations of astronomical constellation pointing, education, scientific research, conferences, business meetings, etc.
The most visible green laser pointer beams can reach target stars, low-level clouds, celestial bodies, constellations, etc. in the shortest possible time. The green laser pointer is especially noticeable at night, reaching at least 5 kilometers in the dark. It can easily be exploited to freely point to constellations.
