Choosing the Perfect Pet Laser Pointer Toy
Generally pet lasers are low power lasers of 1-5 megawatts, it is important to remember that pet lasers can only be low power as low power lasers do no harm. Not suitable for pets, the best choice for pets. Lots of high power. Also, pet laser pointers can be the best choice for dogs and cats. The continuous movement of the laser beam makes the pet happy. For example, the 532nm green laser pointer is widely used in demonstrations of astronomical constellation pointing, education, scientific research, conferences, business meetings, etc. The low-power green laser pointer is just a good tool for the most visible and brightest in the dark, in addition to a series of safety information, the operation of the high power laser pointer should also be highly regarded.

Principle of Laser Lighting
To produce a laser pointer, the following conditions must be met:
1. The population is reversed;
2. It is necessary to have a resonant cavity, which can play the role of optical feedback and form laser oscillation; the Fabry-Perot cavity is the simplest form.
3. The laser must also meet the threshold condition that the gain is greater than the total loss.
Green laser pointers should have spare batteries
Also, many people often use the green laser pointer at noon, but they don't open the door at night. Semiconductor laser pointers are very sensitive to temperature. If the temperature is too low, the laser may not turn on properly. At this time, hold the laser pointer by hand and raise it to 20°C. Conversely, if it is too high, it is best to leave it for a while to let the temperature drop. In addition, the green laser pointer is easy to consume, it is better to buy a battery to charge the laser pointer. Lasers with output powers between 5mW and 500mW are Class IIIb or IEC 3B. Class IIIb lasers cannot be legally advertised as laser pointers or demonstration laser products. Product labels and instructions for use should describe the hazard classification of the product and its output characteristics.
