Class IIIB visible beam lasers have moderate powers of 5 to 499 milliwatts. Class IIIB lasers can cause eye damage. The more powerful the laser, the more likely you are to get hurt. Laser protection goggles are recommended or recommended (depending on the laser output level) as described elsewhere on this page. Class IIIB lasers pose a risk of distraction, glare or flash blindness for pilots and drivers. Do not point the laser at a moving aircraft or vehicle. Always pay attention to the position of the beam. Stay away from people's eyes and heads. Watch out for reflected beams of light from glass and bright surfaces. Avoid targeting or approaching aircraft in the open air. It is important to warm up the laser tube if the operating temperature of the green laser pointer is much lower than expected. In particular, the laser tip should be preheated with a coat or hand. Activating the laser designator in an indoor work environment will return you to a formal or near-formal work environment.
Battery temperature is also a factor. If the battery is placed in a cold place, the output voltage will drop. The drop in voltage reduces the brightness of the laser. Take out the battery, hold it in the palm of your hand and leave it for a moment. When the battery is warm, place it on the pointer. Continuous wave lasers emit light continuously and are used to cut metal plates. The power of the integral over time is great because it's constantly being fired, but the maximum intensity is not that great. It uses heat rather than strength, so to speak. Because pulsed lasers emit light periodically in pulses, the peak intensity is large even if the average energy is not that great. These include femtosecond lasers and attosecond lasers. Increase strength by timely compression. In this case, the intensity can be increased to the PW level. It could be called a high-intensity laser.
