How much do you know about the yellow laser pointer?

The yellow laser's spectrum spreads between 589 nm and 594 nm, and manufacturers have been hoping to effectively reproduce these amazing colors.

The yellow laser's spectrum spreads between 589 nm and 594 nm, and manufacturers have been hoping to effectively reproduce these amazing colors. This is achieved by pumping IR laser diodes into crystals and optical arrays to achieve a wider laser spectrum. When used in winter, the green laser may need to be warmed up for a period of time to reach the best brightness. It can be placed in a pocket and then put in the battery. The continuous lighting time should not exceed 1 minute. To prevent the laser from premature aging or overheating, causing damage to the laser LD or module. The service life of the laser pointer is up to 2 years. However, the laser pointer may also be damaged in a short time. In addition to the problems of the red laser pointer itself, the correct operation of the laser pointer is also very important. Let’s discuss today why the laser pointer can’t light up.

In your opinion, this sounds a bit like a "stranger thing", but in fact, one of the most common uses of high-power laser pointers in the world today is to conduct interesting experiments on materials such as matches, balloons, and tape. When used by experienced people, the burning laser can accomplish a variety of different things. Some videos even depict balloons popping up, including more than 30 balloons in a row. According to the principle of lasers, a shorter-wavelength blue laser pointer can emit brighter light from a longer-wavelength laser at the same power. However, the perspective of 532nm wavelength light is more easily absorbed and more sensitive, while the 405nm blue-violet laser light is weaker to the human eye.

The continuous lighting time of the green laser pointer will vary depending on the output power. The portable green laser will light up within 10 seconds at normal operating temperature (25°). If the working time is prolonged, the output power may increase and attenuate until it does not light up. Long-term operation will damage the laser diode and crystal, or even burn the laser diode. The industrial calibration laser can run continuously for 24 hours at room temperature and cool the system appropriately. The part aimed at the laser should be fixed during operation.
