Using a modified or more powerful laser pointer can lead to serious eye injuries, including permanent vision loss. The human eye is particularly vulnerable to the concentrated beam of a laser, and even a seemingly small increase in power can significantly elevate the risk of damage.
Modifying or tampering with a laser pointer may also have legal consequences. In some countries, certain laser devices are classified as restricted or prohibited, and unauthorized changes or modifications can result in legal penalties.
If you require a higher-powered laser for a specific purpose or application, it's best to purchase a reputable and regulated laser device that meets safety standards. These lasers are designed, manufactured, and tested with safety considerations and appropriate safeguards to minimize risks.
