Remote control of super powerful laser pointer
The apparent brightness of a high power laser pointer beam spot depends not only on the optical power of the laser and the reflectivity of the surface, but also on the color response of the human eye. For the same optical power, green lasers appear brighter than other colors because the human eye is more sensitive to the green region of the spectrum (for low light levels), and the sensitivity decreases as the color becomes redder or bluer.
There are various red, green, blue and infrared laser pointers on the market. Basically laser pointers can be divided into laser diodes and DPSS laser light-emitting gadgets. A general analysis of green and red laser pointers with different fabrication structures is given below. A red laser pointer can be used in almost any interior or low-light situation where pointing out details by hand may be inconvenient, such as in construction work or interior decoration.

Visual effect of 200mw red laser pointer and 20mw green laser pointer
A 200mW red laser pointer can achieve similar visual effects as a 20mW green laser pointer, and the power consumption of both lasers is almost the same. Very powerful lasers are often used as striking pointing devices in school and commercial presentations and visual presentations. Green laser pointers can be used for similar purposes, as well as outdoors during the day or at longer distances. However, green laser pointer are safer to use. Red light travels more easily through air, dust, and water, so higher-power red laser pointers are required to obtain high-visibility red light.
No matter what kind of laser pointer the user chooses, an inferior laser is always not the right choice. Since its development, 200 mW attosecond laser pulses have been used to study various processes, including the excitation and ionization of atoms, and the dynamics of electrons in solids. So far, they have not been used for more complex molecules. One goal is to understand how charge redistributes and how it affects nuclear motion once a molecule is ionized. For the safe operation of the laser pointer, the high power laser gadget is not a perfect recommendation for the user
