The role of laser pointers in medicine
Laser diodes All green high powered laser we provide have a wavelength of 520 nm and are direct diode semiconductor lasers. At present, most of the high-power green laser pointers on the market have a wavelength of 532nm, which is a DPSS (Solid State Diode Pumped) laser. Although this may seem like a small difference, in reality, there is a big difference between the two types of lasers. The 520nm green laser has a significant improvement in power, stability and durability compared to the 532nm green laser. Another problem with using crystals in 532nm green lasers is that not all 808nm infrared laser power is converted to green light. Therefore, using an ordinary 532nm green laser pointer will also emit a lot of infrared rays, which is not good for the eyes. Some laser pointer companies advertise the use of infrared filters to block unnecessary infrared radiation, but this usually equates to greater power loss and low efficiency. Therefore, most 532nm laser pointers do not have infrared filters installed.

There is no need to be too technical, all the gadgets of the laser sight are dedicated to creating visible colored light spots on the intended target surface. Two colors of green laser pointer dominate the market: red and green, each with its own advantages and disadvantages. The red laser is the most common. They require relatively low energy to function, and their construction is relatively simple. Therefore, they are cheaper and compact in size. The disadvantage of red lasers is that they are difficult to see in the sun, only visible at 20-30 feet. Some models provide a pulsed beam, which will flicker from time to time to make the target point easier to find. The green laser provides brighter and easier-to-see target points. Because the human eye is more receptive to this color, some green lasers can be seen under 100 yards of sunlight, as well as in darkness and darkness. However, green lasers are more complicated to manufacture and consume batteries faster. Therefore, they tend to be larger and more expensive.
