Some laser Pointers work better than others. When you need to point at the constellations, you need to use a stronger beam to point at the celestial bodies. Only a high-power laser designator can produce this type of beam. You need much less energy when you want to distract your pet. Other factors, such as the color of the laser and the availability of accessories, will also influence your decision. Blue and green laser pointer are growing in popularity, although red lasers are still the most commonly used lasers in homes. These alternative laser colors have higher power levels and you can use them for remote tasks. The green laser pointer features more efficiently for astronomical classes, while the red pointer handles many everyday tasks.
A yellow laser pointer with a wavelength of 593.5nm has appeared on the market. Based on DPSS technology, two kinds of lasers with wavelength of 1064nm and 1342nm were obtained by adding nonlinear crystal. The complexity of the process makes the yellow laser pointer unstable and inefficient. The output power of temperature changes is 1-10MW, and there will be mode jump whether it is overheated or undercooled. This is because the size of the laser designator does not provide the required temperature stability and component cooling.
