The method of laser infrared treatment?

Some irresponsible businesses mislead customers for profit. We cannot stop this, but we must explain some facts. Generally speaking, we can realize that the output power of the water-cooled solid-state green laser is 5W, and the output power of the laser flashlight is 1.6W. But 30000mW (30W) does not exist! First, you need to understand what your goals are. If the application is a demonstration, a green laser of 10 to 100 mW is sufficient. If it needs to be used for astronomy or outdoor survival, 30-500mW is recommended (the maximum astronomy cannot exceed 200mW, otherwise it will easily cause pilot accidents). If you must conduct a high powered laser experiment, you can choose the wattage that best suits you, and remember that there is no such thing as a 30,000mW green laser pointer.
