Is the 3w blue laser pointer a high-power laser pointer?
Under the same output power, such as 100mW, a green laser is 5 to 10 times brighter than any other color green laser pointer. Color is measured in nanometers (nM) in the visible spectrum, and the brightness of each color is different under the same output power. If there is no special camera and imaging equipment, infrared is invisible to the human eye, and it is usually used in military and research. Because lasers produce condensed light, the nanometer (nM) scale is used to measure color in the visible spectrum. Green at 532nm is the brightest color of the human eye. This means that a green laser pointer with the same output power as any other color will be 7 to 10 times brighter. Due to this fact, green lasers are currently the most popular and commonly needed color, simply because they look vivid.

Older keychain lasers are less than 5mW, usually 1mW on average, but now handheld high powered laser can generate more than 6W of power. This means that lasers can be seen for more than 20 miles in a clear line of sight at night, can illuminate matches, and can blow up balloons at a distance. This creates a whole new field for use as a recommended tool for laser pointers. From search and rescue operations, construction workers, pest control airports, homeowners to fear of non-lethal geese, police and military training and activities, and more. Not to mention the traditional star gaze and astronomy that all laser lovers experiment at home and school. When it comes to laser applications today, please keep an open mind.
