How to check whether the laser pointer is damaged?
You can try to chase the geese outside to scare them, but this is not sustainable after one or two. First of all, you must leave the house personally to chase the geese. Secondly, they will go into the water and stare at you. Third, they will come back as soon as you leave. So, have you been cleaning goose droppings or picking up goose droppings from your shoes? Fortunately, input a high-power laser pointer. Now that we understand the several ways that high powered laser are a good anti-goose tool, we need to understand the specific types of lasers that are most suitable for this type of work. Color is very important, but so is the power level. Generally speaking, at the same power, a green laser is 5 to 7 times brighter than any other color laser. Therefore, if we have a 500mW green laser pointer, it will be 5 times brighter than a 500mW blue or red laser and 7 times brighter than a 500mW purple laser. So green is your best choice.

The team’s technology uses lasers to measure the material’s influence on the polarization state of light, which is related to the direction of the oscillating electric field of the light reflected by the material. For example, if the sun's rays reflect a rubber ball, the electric field of the incident light can oscillate vertically. But certain properties of the spherical surface, such as roughness, can cause it to oscillate horizontally or reflect in completely different directions. The same material can have multiple polarization effects, depending on the angle at which the light illuminates it.
